Struct NamedId 

pub struct NamedId(pub usize);

Identifier used to correlate a named import to a host-defined value.

This type is a small newtype wrapper around a usize, its only field which is also public. Embeders define the meaning of this value and are in control of both creating this an interpreting it. Creation of NamedId happens in functions like wasmtime_wasi::p3::add_named_to_linker where embedders will allocate a NamedId for all recognized named imports. Interpreting a NamedId happens later in traits such as WasiNamedView where the id is passed back to the embedder and a corresponding context must be returned.

Internally the wasmtime-wasi crate does not inspect the internal field here nor ever create one. Embedders are solely responsible for managing this id and its conetnts.
