Method get_export

crates/wasmtime/src/runtime/instance.rs:438–444

Looks up an exported [`Extern`] value by name. This method will search the module for an export named `name` and return the value, if found. Returns `None` if there was no export named `name`. # Panics Panics if `store` does not own this instance. # Why does `get_export` take a mutable context? This method requires a mutable context because an instance's exports are lazily populated, and we
