Envk::mem::AllocationAlgorithm

pub enum AllocationAlgorithm {
    Tlsf,
    Linear,
}

Placement metadata for custom pools and host-only virtual blocks.

Contract

Placement metadata for custom pools and host-only virtual blocks.

Linear placement appends after the current tail; middle holes are not reused. Releasing all regions restarts the range. Last-in-first-out release rewinds a stack; a single-block pool also supports ring and double-stack lifetimes. Strategy flags affect TLSF only. These are placement rules, not GPU lifetime tracking or latency guarantees.

Methods and associated items

clone

Method

fn clone(&self) -> AllocationAlgorithm

Returns a duplicate of the value. Read more

fmt

Method

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter. Read more

default

Method

fn default() -> AllocationAlgorithm

Returns the “default value” for a type. Read more

eq

Method

fn eq(&self, other: &AllocationAlgorithm) -> bool

Tests for self and other values to be equal, and is used by ==.

Envk::mem::AllocationPolicy

pub enum AllocationPolicy {
    Separate,
    Automatic,
    Pooled {
        block_size: u64,
    },
    Adaptive {
        block_size: u64,
        min_block_size: u64,
    },
}

Managed resource storage policy. Required or preferred native dedication takes precedence.

Contract

Fields

Pooled.field.block_size

Field

block_size: u64

No public source comment is attached to this declaration.

Adaptive.field.block_size

Field

block_size: u64

No public source comment is attached to this declaration.

Adaptive.field.min_block_size

Field

min_block_size: u64

No public source comment is attached to this declaration.

Variants

Separate

Variant

Separate

No public source comment is attached to this declaration.

Automatic

Variant

Automatic

Heap-sized default pools with pinned VMA growth, reuse and separate fallback.

Pooled

Variant

Pooled

Reuse ordinary buffer blocks with this exact native size. No block shrinking. Requests larger than the block use separate storage.

Adaptive

Variant

Adaptive

Try bounded power-of-two block sizes, shrinking only on recoverable storage failure. Large regions and exhausted block attempts fall back to separate storage.
