Struct OffscreenBudget 

pub struct OffscreenBudget {
    pub max_targets: usize,
    pub max_total_pixels: u64,
    pub current_pixels: u64,
    pub current_targets: usize,
}

Budget for offscreen render targets. Prevents OOM on mobile GPUs by enforcing a maximum number of concurrent offscreen targets and a maximum total pixel count.

Fields

max_targets: usize

Maximum number of concurrent offscreen targets.

max_total_pixels: u64

Maximum total pixel count across all offscreen targets.

current_pixels: u64

Current total pixel count.

current_targets: usize

Current number of allocated targets.

Implementations

impl OffscreenBudget

pub fn mobile() -> Self

pub fn release(&mut self, width: u32, height: u32)

Release an offscreen target.

pub fn reset(&mut self)

Reset the budget (e.g., on frame boundary).

pub fn is_exhausted(&self) -> bool

Returns true if the budget is exhausted.
