Data.KindID

Description

Similar to Data.TypeID, but the type is statically determined in the type level.

When using TypeID, if we want to check if the type matches, we usually need to get the prefix of the TypeID and compare it with the desired prefix at runtime. However, with Haskell's type system, we can do this at compile time instead. We call this TypeID with compile-time prefix a KindID.

Of course, that would require the desired prefix to be known at compile time. This is actually quite common, especially when we are using one prefix for one table in the database.

For example, suppose we have a function that takes a KindID with the prefix "user", it may have a signature like this: f :: KindID "user" -> IO ()

Then if we try to pass in a KindID with the prefix "post", the compiler will complain, thus removing the runtime check and the associated overhead.

All the prefixes are type-checked at compile time, so if we try to pass in invalid prefixes, the compiler (again) will complain.

This module contains functions to generate and parse these type-level TypeIDs as well as conversion functions to and from the usual term-level TypeIDs. These functions are usually used with a type application, e.g.

do
  kindID <- genKindID @"user"
  ...

It is a re-export of Data.KindID.V7.

Synopsis

Data types

type KindID = KindID' 'V7 Source #

A type alias for the default KindID implementation with UUIDv7.

data KindID' (version :: UUIDVersion) prefix Source #

A TypeID with the prefix encoded at type level.

It is dubbed KindID because the prefix here is a data kind rather than a type.

getPrefix :: IDType a => a -> Text Source #

Get the prefix of the identifier.

getUUID :: IDType a => a -> UUID Source #

Get the UUID suffix of the identifier.

getTime :: IDType a => a -> Word64 Source #

Get the timestamp of the identifier. Returns 0 if the identifier is not timestamp-based.

KindID generation (KindID-specific)

genKindID :: (ToPrefix prefix, ValidPrefix (PrefixSymbol prefix), MonadIO m) => m (KindID prefix) Source #

Generate a new KindID from a prefix.

It throws a TypeIDError if the prefix does not match the specification, namely if it's longer than 63 characters or if it contains characters other than lowercase latin letters.

genKindID' :: (ToPrefix prefix, ValidPrefix (PrefixSymbol prefix), MonadIO m) => m (KindID prefix) Source #

Generate a new KindID from a prefix based on stateless UUIDv7.

See the documentation of genUUID' for more information.

genKindIDs :: (ToPrefix prefix, ValidPrefix (PrefixSymbol prefix), MonadIO m) => Word16 -> m [KindID prefix] Source #

Generate a list of KindIDs from a prefix.

It tries its best to generate KindIDs at the same timestamp, but it may not be possible if we are asking too many UUIDs at the same time.

It is guaranteed that the first 32768 KindIDs are generated at the same timestamp.

decorateKindID :: (ToPrefix prefix, ValidPrefix (PrefixSymbol prefix)) => UUID -> KindID prefix Source #

Obtain a KindID from a prefix and a UUID.

KindID generation (class methods)

genID :: forall a m. (IDGen a, MonadIO m) => GenFunc (IDGenPrefix a) (IDGenReq a (m a)) Source #

Generate a new identifier with the given prefix.

genID' :: forall a m. (IDGen a, MonadIO m) => GenFunc (IDGenPrefix a) (IDGenReq a (m a)) Source #

Similar to genID, but stateless. It can be a faster implementation than genID, but it does not guarantee any stateful property, such as monotonically increasing for UUIDv7-based identifiers.

The default implementation is the same as genID.

genIDs :: forall a m. (IDGen a, MonadIO m) => GenFunc (IDGenPrefix a) (IDGenReq a (Word16 -> m [a])) Source #

Generate a list of identifiers with the given prefix.

decorate :: forall a. IDGen a => GenFunc (IDGenPrefix a) (UUID -> ResWithErr (IDGenPrefix a) a) Source #

Generate a new identifier with the given prefix and UUID suffix.

Validation (KindID-specific)

checkKindID :: (ToPrefix prefix, ValidPrefix (PrefixSymbol prefix)) => KindID prefix -> Maybe TypeIDError Source #

Check if the prefix is valid and the suffix UUID has the correct v7 version and variant.

checkKindIDWithEnv :: (ToPrefix prefix, ValidPrefix (PrefixSymbol prefix), MonadIO m) => KindID' 'V7 prefix -> m (Maybe TypeIDError) Source #

Similar to checkKindID, but also checks if the suffix UUID is generated in the past.

Validation (class methods)

checkID :: forall a. IDGen a => a -> Maybe TypeIDError Source #

Check the validity of the identifier.

checkIDWithEnv :: forall a m. (IDGen a, MonadIO m) => a -> m (Maybe TypeIDError) Source #

Check the validity of the identifier, potentially with impure criteria.

Encoding & decoding (KindID-specific)

toString :: (ToPrefix prefix, ValidPrefix (PrefixSymbol prefix)) => KindID prefix -> String Source #

Pretty-print a KindID. It is id2String with concrete type.

toText :: (ToPrefix prefix, ValidPrefix (PrefixSymbol prefix)) => KindID prefix -> Text Source #

Pretty-print a KindID to strict Text. It is id2Text with concrete type.

toByteString :: (ToPrefix prefix, ValidPrefix (PrefixSymbol prefix)) => KindID prefix -> ByteString Source #

Parse a KindID from its String representation. It is string2ID with concrete type.

parseText :: forall prefix. (ToPrefix prefix, ValidPrefix (PrefixSymbol prefix)) => Text -> Either TypeIDError (KindID prefix) Source #

parseByteString :: forall prefix. (ToPrefix prefix, ValidPrefix (PrefixSymbol prefix)) => ByteString -> Either TypeIDError (KindID prefix) Source #

parseStringM :: (ToPrefix prefix, ValidPrefix (PrefixSymbol prefix), MonadIO m) => String -> m (KindID prefix) Source #

Parse a KindID from its String representation, throwing an error when the parsing fails. It is string2IDM with concrete type.

parseTextM :: (ToPrefix prefix, ValidPrefix (PrefixSymbol prefix), MonadIO m) => Text -> m (KindID prefix) Source #

Parse a KindID from its string representation as a strict Text, throwing an error when the parsing fails. It is text2IDM with concrete type.

parseByteStringM :: (ToPrefix prefix, ValidPrefix (PrefixSymbol prefix), MonadIO m) => ByteString -> m (KindID prefix) Source #

Parse a KindID from its string representation as a lazy ByteString, throwing an error when the parsing fails. It is byteString2IDM with concrete type.

id2String :: IDConv a => a -> String Source #

Pretty-print the identifier to a String.

string2IDM :: (IDConv a, MonadIO m) => String -> m a Source #

Parse the identifier from its String representation, throwing an error when the parsing fails.

text2IDM :: (IDConv a, MonadIO m) => Text -> m a Source #

Parse the identifier from its string representation as a strict Text, throwing an error when the parsing fails.

byteString2IDM :: (IDConv a, MonadIO m) => ByteString -> m a Source #

Parse the identifier from its string representation as a lazy ByteString, throwing an error when the parsing fails.

Type-level & term-level conversion

toTypeID :: (ToPrefix prefix, ValidPrefix (PrefixSymbol prefix)) => KindID prefix -> TypeID Source #

Convert a KindID to a TypeID.

fromTypeID :: (ToPrefix prefix, ValidPrefix (PrefixSymbol prefix)) => TypeID -> Maybe (KindID prefix) Source #
