Darcs.Patch.Prim.Named

Description

Wrapper for prim patches to give them an identity derived from the identity of the containined Named patch.

Synopsis

type NamedPrim = PrimWithName PrimPatchId
data PrimPatchId
namedPrim :: PrimPatchId -> p wX wY -> NamedPrim p wX wY
positivePrimPatchIds :: PatchInfo -> [PrimPatchId]
anonymousNamedPrim :: p wX wY -> NamedPrim p wX wY
unsafePrimPatchId :: TestOnly => Int -> SHA1 -> PrimPatchId
prop_primPatchIdNonZero :: PrimPatchId -> Bool

Documentation

type NamedPrim = PrimWithName PrimPatchId Source #

data PrimPatchId Source #

Signed patch identity. The SHA1 hash of the non-inverted meta data (PatchInfo) plus an Int for the sequence number within the named patch, starting with 1. The Int gets inverted together with the patch and must never be 0 else we could not distinguish between the patch and its inverse.

namedPrim :: PrimPatchId -> p wX wY -> NamedPrim p wX wY Source #

positivePrimPatchIds :: PatchInfo -> [PrimPatchId] Source #

Create an infinite list of positive PrimPatchIds.

anonymousNamedPrim :: p wX wY -> NamedPrim p wX wY Source #

unsafePrimPatchId :: TestOnly => Int -> SHA1 -> PrimPatchId Source #

This should only be used for testing, as it exposes the internal structure of a PrimPatchId.
