Struct RegionConfig 

pub struct RegionConfig {
    pub initial_capacity: usize,
    pub growth_factor: f64,
    pub max_regions: usize,
}

Configuration for a RegionAllocator.

Fields

initial_capacity: usize

Initial capacity (bytes) of each newly created region.

growth_factor: f64

Multiplicative growth factor when a region must be expanded. Values outside (1.0, 16.0] are clamped.

max_regions: usize

Maximum number of live regions the allocator will manage.

Implementations

impl RegionConfig

pub fn new( initial_capacity: usize, growth_factor: f64, max_regions: usize, ) -> Self

Construct a configuration, clamping growth_factor to (1.0, 16.0].

pub fn grow(&self, current: usize) -> usize

Return next capacity after growing by the configured factor.
