Struct StretchSizeKey 

pub struct StretchSizeKey {
    pub size: SizeKey,
    pub fills_width: bool,
    pub fills_height: bool,
}

How to compute the effective stretch size for an image primitive, per axis. FillsPrim resolves to the (snapped) prim-rect extent at frame-build so the value sent to the GPU lands on the snapped pixel grid. Explicit keeps the gecko-specified value verbatim. Per-axis because gecko can specify a background tile that fills the prim on one axis but tiles on the other (e.g. background-repeat: repeat-y with background-size: 116.8px 0.8px).

Fields

size: SizeKey

fills_width: bool

fills_height: bool

Implementations

impl StretchSizeKey

pub fn fills_prim() -> Self

Both axes fill the prim. The stored size is unused; normalised to zero so different prim sizes still intern to the same key.

Trait Implementations

impl Clone for StretchSizeKey

fn clone(&self) -> StretchSizeKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StretchSizeKey

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

Formats the value using the given formatter.

impl From<StretchSizeKey> for StretchSize

fn from(k: StretchSizeKey) -> Self

Converts to this type from the input type.

impl Hash for StretchSizeKey

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

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 MallocSizeOf for StretchSizeKey

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself.

impl PartialEq for StretchSizeKey

fn eq(&self, other: &StretchSizeKey) -> 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.

impl Serialize for StretchSizeKey

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for StretchSizeKey
