get

refStringGet

Arguments

:: (HasCallStack, MonadIO m)

=> RefString

refstr: the RefString to fetch from

-> Word64

length: return length here, optionally

-> m Text

Returns: The C string held by refstr.

Get a pointer to the private string inside a refstr. Handy for language bindings.

See also: valueGetRefString.

new

refStringNew

Arguments

:: (HasCallStack, MonadIO m)

=> Text

str: string to store

-> m RefString

Returns: the new RefString, or NULL on error.

Create a new refstring. These are reference-counted immutable strings, used to store string data in vips image metadata.

Strings must be valid utf-8; use blob for binary data.

getRefStringArea :: MonadIO m => RefString -> m Area

Get the value of the “area” field. When overloading is enabled, this is equivalent to

get refString #area
