InstanceAllocationStrategy

Enum InstanceAllocationStrategy 

Source
#[non_exhaustive]
pub enum InstanceAllocationStrategy { OnDemand, Pooling(PoolingAllocationConfig), }
Expand description

Represents the module instance allocation strategy to use.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

OnDemand

The on-demand instance allocation strategy.

Resources related to a module instance are allocated at instantiation time and immediately deallocated when the Store referencing the instance is dropped.

This is the default allocation strategy for Wasmtime.

§

Pooling(PoolingAllocationConfig)

The pooling instance allocation strategy.

A pool of resources is created in advance and module instantiation reuses resources from the pool. Resources are returned to the pool when the Store referencing the instance is dropped.
