#[non_exhaustive]
pub enum WasmtimeInstantiationStrategy {
PoolingCopyOnWrite,
RecreateInstanceCopyOnWrite,
Pooling,
RecreateInstance,
LegacyInstanceReuse,
}
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.
LegacyInstanceReuse
Legacy instance reuse mechanism. DEPRECATED. Will be removed. Do not use.
