#[non_exhaustive]pub enum WasmtimeInstantiationStrategy {
PoolingCopyOnWrite,
RecreateInstanceCopyOnWrite,
Pooling,
RecreateInstance,
}
Expand description
The instantiation strategy to use for the WASM executor.
All of the CoW strategies (with CopyOnWrite
suffix) are only supported when either:
a) we’re running on Linux,
b) we’re running on an Unix-like system and we’re precompiling
our module beforehand and instantiating from a file.
If the CoW variant of a strategy is unsupported the executor will fall back to the non-CoW equivalent.
Variants (Non-exhaustive)§
This enum is marked as non-exhaustive
PoolingCopyOnWrite
Pool the instances to avoid initializing everything from scratch on each instantiation. Use copy-on-write memory when possible.
This is the fastest instantiation strategy.
RecreateInstanceCopyOnWrite
Recreate the instance from scratch on every instantiation. Use copy-on-write memory when possible.
Pooling
Pool the instances to avoid initializing everything from scratch on each instantiation.
RecreateInstance
Recreate the instance from scratch on every instantiation. Very slow.
