Struct wasmtime_runtime::PoolingInstanceAllocator

pub struct PoolingInstanceAllocator { /* private fields */ }

Implements the pooling instance allocator.

This allocator internally maintains pools of instances, memories, tables, and stacks.

Note: the resource pools are manually dropped so that the fault handler terminates correctly.

Implementations

impl PoolingInstanceAllocator

pub fn new( strategy: PoolingAllocationStrategy, instance_limits: InstanceLimits, stack_size: usize, tunables: &Tunables, async_stack_zeroing: bool ) -> Result<Self>

Creates a new pooling instance allocator with the given strategy and limits.
