Struct IccCache 

pub struct IccCache { /* private fields */ }

Per-document cache of ICCBased profile streams → compiled transforms, keyed by the profile stream’s object id AND the rendering intent (the same profile may be requested under different intents on one page). Failures are cached as None so a malformed profile is parsed (and warned about) once.

Implementations

impl IccCache

pub fn new() -> IccCache

pub fn get_or_build( &mut self, id: ObjectId, intent: RenderIntent, data: impl FnOnce() -> Option<Vec<u8>>, ) -> Option<Arc<IccTransform>>

The cached transform for profile stream id under intent, building it from the bytes returned by data on first use. data returning None (unresolvable stream) also caches as a failure.

Trait Implementations

impl Debug for IccCache

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for IccCache

fn default() -> IccCache

Returns the “default value” for a type.
