Methods

Overloaded methods

compare

oIdCompare Source #

Arguments

:: (HasCallStack, MonadIO m)
=> OId	`a`: first `OId`.
-> OId	`b`: second `OId`.
-> m Int32	Returns: <0, 0, >0 if a < b, a == b, a > b.

Compare two OId structures.

copy

oIdCopy Source #

Arguments

:: (HasCallStack, MonadIO m)
=> OId	`oid`: a `OId`.
-> m (Maybe OId)	Returns: a newly allocated `OId`.

Copies oid into a newly allocated OId.

equal

oIdEqual Source #

Arguments

:: (HasCallStack, MonadIO m)
=> OId	`a`: a `OId`.
-> OId	`b`: a `OId`.
-> m Bool	Returns: `True` if `a` and `b` are equal, `False` otherwise

Compares two OId for equality.

free

oIdFree Source #

Arguments

:: (HasCallStack, MonadIO m)
=> OId	`oid`: a `OId`.
-> m ()

Frees oid.

hasPrefix

oIdHasPrefix Source #

Arguments

:: (HasCallStack, MonadIO m)
=> OId	`oid`: a `OId`.
-> Text	`prefix`: a prefix.
-> m Bool	Returns: `True` if the id has the given prefix, `False` otherwise.

Check whether the object id has a given prefix. Note that the prefix is specified in hexadecimal ASCII.

hash

oIdHash Source #

Arguments

:: (HasCallStack, MonadIO m)
=> OId	`oid`: a `OId`.
-> m Word32	Returns: the hash value

Computes a hash value for a git object identifier.

isZero

oIdIsZero Source #

Arguments

:: (HasCallStack, MonadIO m)
=> OId	`oid`: a `OId`.
-> m Bool	Returns: `True` if the oid contains only zeros, `False` otherwise.

Get whether the oid contains only zeros.

newFromRaw

oIdNewFromRaw Source #

Arguments

:: (HasCallStack, MonadIO m)
=> ByteString	`raw`: the raw input bytes to be copied.
-> m (Maybe OId)	Returns: a newly allocated `OId` or `Nothing` on error.

Creates a new OId from a raw oid.

newFromString

oIdNewFromString Source #

Arguments

:: (HasCallStack, MonadIO m)
=> Text	`str`: input hex string; must be pointing at the start of the hex sequence and have at least the number of bytes needed for an oid encoded in hex (40 bytes).
-> m (Maybe OId)	Returns: a newly allocated `OId` or `Nothing` on error.

Parses a hex formatted object id into a OId.

toString

oIdToString Source #

Arguments

:: (HasCallStack, MonadIO m)
=> OId	`oid`: a `OId`.
-> m (Maybe Text)	Returns: a newly allocated string representing `oid` or `Nothing`.

Converts oid into a readable string.
