Method module_version

crates/wasmtime/src/config.rs:2094–2106

Configure the version information used in serialized and deserialized [`crate::Module`]s. This effects the behavior of [`crate::Module::serialize()`], as well as [`crate::Module::deserialize()`] and related functions. The default strategy is to use the wasmtime crate's Cargo package version.
