Enum InstanceAllocationStrategy 

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

Represents the module instance allocation strategy to use.

Variants (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.

Implementations
