Method get_export

crates/wasmtime/src/runtime/module.rs:878–887

Looks up an export in this [`Module`] by name. This function will return the type of an export with the given name. # Examples There may be no export with that name: ``` # use wasmtime::*; # fn main() -> Result<()> { # let engine = Engine::default(); let module = Module::new(&engine, "(module)")?; assert!(module.get_export("foo").is_none()); # Ok(()) # } ``` When there is an export with that
