A GPatternSpec struct is the 'compiled' form of a pattern. This structure is opaque and its fields cannot be accessed directly.
- newtype PatternSpec = PatternSpec (ManagedPtr PatternSpec)
- noPatternSpec :: Maybe PatternSpec
- patternSpecEqual :: (HasCallStack, MonadIO m) => PatternSpec -> PatternSpec -> m Bool
- patternSpecFree :: (HasCallStack, MonadIO m) => PatternSpec -> m ()

equal
:: (HasCallStack, MonadIO m) | |
=> PatternSpec |
|
-> PatternSpec |
|
-> m Bool | Returns: Whether the compiled patterns are equal |
Compares two compiled pattern specs and returns whether they will match the same set of strings.
free
:: (HasCallStack, MonadIO m) | |
=> PatternSpec |
|
-> m () |
Frees the memory allocated for the PatternSpec
