ProjectM36.HashSecurely
Description
A unified class for walking the database structure to produce a hash used for Merkle trees and validation.
Synopsis
- newtype SecureHash = SecureHash {}
- class HashBytes a where
- data SHash = forall a.HashBytes a => SHash !a
- hashBytesL :: Foldable f => Ctx -> ByteString -> f SHash -> Ctx
- hashTransaction :: Transaction -> Set Transaction -> MerkleHash
- mkDDLHash :: DatabaseContext -> Map RelVarName Relation -> SecureHash

hashBytesL :: Foldable f => Ctx -> ByteString -> f SHash -> Ctx Source #
hashTransaction :: Transaction -> Set Transaction -> MerkleHash Source #
Hash a transaction within its graph context to create a Merkle hash for it.
mkDDLHash :: DatabaseContext -> Map RelVarName Relation -> SecureHash Source #
Return a hash of just DDL-specific (schema) attributes. This is useful for determining if a client has the appropriate updates needed to work with the current schema.
