Module wasmtime_environ::prelude

Rust module prelude for Wasmtime crates.

Wasmtime crates that use no_std use core::prelude::* by default which does not include alloc-related functionality such as String and Vec. To have similar ergonomics to std and additionally group up some common functionality this module is intended to be imported at the top of all modules with:

use crate::*;

Externally for crates that depend on wasmtime-types they should have this in the root of the crate:

use wasmtime_types::prelude;

and then use crate::* works as usual.
