HashAddressed.Directory

Contents

Synopsis

Type

Arguments

:: HashFunction	Which hash function to use
-> FilePath	Directory where content-addressed files are stored
-> ContentAddressedDirectory

Specification of a content-addressed directory

Write operations

Arguments

:: ContentAddressedDirectory	The content-addressed file store to write to; see `init`
-> ByteString	The content to write to the store
-> IO WriteResult	The file path where the contents of the lazy byte string now reside. This path includes the store directory.

Write a lazy byte string to a content-addressed directory

This is a simplified variant of writeStreaming.

Arguments

:: ContentAddressedDirectory	The content-addressed file store to write to; see `init`
-> (forall m. MonadIO m => (ByteString -> m ()) -> m ())	Monadic action which is allowed to emit `ByteString`s and do I/O. If this action throws an exception, nothing will be written to the store.
-> IO WriteResult

Write a stream of strict byte strings to a content-addressed directory

This is a simplified variant of writeEither.

Arguments

:: ContentAddressedDirectory	The content-addressed file store to write to; see `init`
-> (forall m. MonadIO m => (ByteString -> m ()) -> m (Either bad good))	Monadic action which is allowed to emit `ByteString`s and do I/O. The action should return `Right` once the content has been successfully written. If the action returns `Left` or throws an exception, then nothing will be committed to the store.
-> IO (Either bad (good, WriteResult))

Write a stream of strict byte strings to a content-addressed directory
