Struct MemoryBudget 

pub struct MemoryBudget { /* private fields */ }

Implementations

impl MemoryBudget

pub fn new(ceiling: u64) -> MemoryBudget

pub fn admit( &self, bytes: u64, alone: bool, stop: impl Fn() -> bool, ) -> Option<Permit<'_>>

Wait for room for bytes; alone holds the device exclusively (the retry of a render that ran out of memory). None when stop turns true while waiting (the process is ending): the caller renders on the CPU.

pub fn out_of_memory(&self)

A render ran out of device memory: halve the budget (not below what one render needs).

pub fn succeeded(&self)

A render succeeded: grow the budget back by a sixteenth of its ceiling.
