Struct TierMask 

pub struct TierMask(/* private fields */);

Bitmask tracking which tiers have valid copies of data

Implementations

impl TierMask

pub const NONE: TierMask

Empty mask (no valid copies)

pub const VRAM: TierMask

VRAM tier bit

pub const HOST: TierMask

Host tier bit

pub const DISK: TierMask

Disk tier bit

pub fn from_tier(tier: Tier) -> Self

Create a new mask from a tier

pub fn has(&self, tier: Tier) -> bool

Check if tier has valid copy

pub fn add(&mut self, tier: Tier)

Add a tier to the mask

pub fn remove(&mut self, tier: Tier)

Remove a tier from the mask

pub fn union(&self, other: TierMask) -> TierMask

Union of two masks

pub fn count(&self) -> u32

Count number of valid tiers

pub fn any(&self) -> bool

Check if any tier has valid copy

pub fn fastest(&self) -> Option<Tier>

Get the fastest tier with valid copy

pub fn iter(&self) -> impl Iterator<Item = Tier>

Iterator over valid tiers

Trait Implementations

impl Clone for TierMask

fn clone(&self) -> TierMask

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TierMask

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

Formats the value using the given formatter.

impl Default for TierMask

fn default() -> TierMask

Returns the “default value” for a type.

impl PartialEq for TierMask

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