RetainedBudget

frust_engine::cache::retained

Struct RetainedBudget

pub struct RetainedBudget {
    pub bytes: u64,
}

Expand description

How many bytes of retained pages a store may hold at once.

Fields§

§bytes: u64

The ceiling, in bytes of texture.

Implementations§

impl RetainedBudget

pub const MOBILE: Self

A phone’s budget: 32 MiB, three 1080x2400 full-screen pages — what a navigator transition (the outgoing and the incoming page) needs with one to spare.

pub const MOBILE_LARGE: Self

A phone with at least 4 GiB of memory: 64 MiB.

pub const DESKTOP: Self

A desktop-class adapter: 256 MiB, several 4K-window pages.

pub fn for_tier(tier: AtlasTier) -> Self

The budget tier stands for — the image atlas’s own tier read (cache::images::choose_tier), so one adapter answers the mobile-or-desktop question once for both caches.

pub fn for_caps(caps: &TierCaps) -> Self

The budget for caps’ adapter on this device, or FRUST_ENGINE_RETAINED_BUDGET_MB when it is set.
