Source 
pub trait TryAllocateBuffer<'a> {
    type Buffer;

    // Required method
    fn try_allocate_buffer(
        &'a self,
        size: usize,

}
Expand description

A trait for buffer allocators that support asynchronous buffer allocation via event listeners.

Required Associated Types§

Source

type Buffer

Required Methods§

Source

fn try_allocate_buffer( &'a self, size: usize, ) -> Result<Self::Buffer, EventListener>

Attempts to allocate a buffer of size bytes. Returns an EventListener to wait on if memory is temporarily unavailable.

Provided Methods§

Source

fn allocate_buffer_sync(&'a self, size: usize) -> Self::Buffer

Allocates a buffer synchronously, blocking the current thread until memory is available.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
