Enum BudgetType

#[repr(u8)]
enum BudgetType {
    SharedColor8Linear = 0,
    SharedColor8Nearest = 1,
    SharedColor8Glyphs = 2,
    SharedAlpha8 = 3,
    SharedAlpha8Glyphs = 4,
    SharedAlpha16 = 5,
    Standalone = 6,
}

The different budget types for the texture cache. Each type has its own memory budget. Once the budget is exceeded, entries with automatic eviction are evicted. Entries with manual eviction share the same budget but are not evicted once the budget is exceeded. Keeping separate budgets ensures that we don’t evict entries from unrelated textures if one texture gets full.

Variants

SharedColor8Linear = 0

SharedColor8Nearest = 1

SharedColor8Glyphs = 2

SharedAlpha8 = 3

SharedAlpha8Glyphs = 4

SharedAlpha16 = 5

Standalone = 6

Trait Implementations

impl Clone for BudgetType

fn clone(&self) -> BudgetType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BudgetType

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

Formats the value using the given formatter.

impl PartialEq for BudgetType

fn eq(&self, other: &BudgetType) -> 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 BudgetType

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
