Enum Cached 

pub enum Cached {
    Added(usize),
    Changed(usize),
    Cleared(usize),
}

Successful method of caching of the queue, returned from cache_rects.

Variants

Added(usize)

Added some rects into the cache without affecting any of the already cached rects from previous queues. Contains the number of rects that was added to the cache.

Changed(usize)

Added some rects into the cache, but removed some glyphs from previous queues. Contains the number of rects that was added to the cache.

Cleared(usize)

Added all rects into the cache, by clearing all rects from previous queues. Contains the number of rects contained in the cache.

Implementations

impl Cached

pub fn len(&self) -> usize

Return the number of rects that was added to the cached.

This includes rects that was reordered, in the cause of Cached::Cleared.

Trait Implementations

impl Clone for Cached

fn clone(&self) -> Cached

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Cached

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

Formats the value using the given formatter.

impl Hash for Cached

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 Ord for Cached

fn cmp(&self, other: &Cached) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Cached

fn eq(&self, other: &Cached) -> 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 PartialOrd for Cached

fn partial_cmp(&self, other: &Cached) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
