Module uefi::alloc

This module implements Rust’s global allocator interface using UEFI’s memory allocation functions.

Enabling the alloc optional feature in your app will allow you to use Rust’s higher-level data structures, like boxes, vectors, hash maps, linked lists and so on.

Usage

Call the init function with a reference to the boot services table. Failure to do so before calling a memory allocating function will panic.

Call the exit_boot_services function before exiting UEFI boot services. Failure to do so will turn subsequent allocation into undefined behaviour.

Structs

Allocator

Allocator which uses the UEFI pool allocation functions.

Functions

exit_boot_services

Notify the allocator library that boot services are not safe to call anymore

init^⚠

Initializes the allocator.
