Struct wasmtime::ImportType

source · 
pub struct ImportType<'module> { /* private fields */ }
Available on crate feature runtime only.
Expand description

A descriptor for an imported value into a wasm module.

This type is primarily accessed from the Module::imports API. Each ImportType describes an import into the wasm module with the module/name that it’s imported from as well as the type of item that’s being imported.
