Enum CachingHint

#[repr(u32)]
pub enum CachingHint {
    Allow = 0,
    Disallow = 1,
}

CachingHint selects whether Skia may internally cache Bitmap generated by decoding Image, or by copying Image from GPU to CPU. The default behavior allows caching Bitmap.

Choose CachingHint::Disallow if Image pixels are to be used only once, or if Image pixels reside in a cache outside of Skia, or to reduce memory pressure.

Choosing CachingHint::Allow does not ensure that pixels will be cached. Image pixels may not be cached if memory requirements are too large or pixels are not accessible.

Variants

Allow = 0

Disallow = 1

Trait Implementations

impl Clone for SkImage_CachingHint

fn clone(&self) -> SkImage_CachingHint

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SkImage_CachingHint

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

Formats the value using the given formatter.

impl Hash for SkImage_CachingHint

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for SkImage_CachingHint

fn eq(&self, other: &SkImage_CachingHint) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
