Struct vm_allocator::IdAllocator

source · [−]

pub struct IdAllocator { /* private fields */ }

Expand description

An unique ID allocator that allows management of IDs in a given interval.

Implementations

impl IdAllocator

pub fn new(range_base: u32, range_end: u32) -> Result<Self>

Creates a new instance of IdAllocator that will be used to manage the allocation and release of ids from the interval specified by range_base and range_end

pub fn allocate_id(&mut self) -> Result<u32>

Allocate an ID from the managed range. We first try to reuse one of the IDs released before. If there is no ID to reuse we return the next available one from the managed range.

pub fn free_id(&mut self, id: u32) -> Result<u32>

Frees an id from the managed range.
