Function encode

Source
pub fn encode(resolve: &Resolve, package: PackageId) -> Result<Vec<u8>>
Expand description

Encodes the given package within resolve to a binary WebAssembly representation.

This function is the root of the implementation of serializing a WIT package into a WebAssembly representation. The wasm representation serves two purposes:

  • One is to be a binary encoding of a WIT document which is ideally more stable than the WIT textual format itself.
  • Another is to provide a clear mapping of all WIT features into the component model through use of its binary representation.

The resolve provided is a set of packages and types and such and the package argument is an ID within the world provided. The documents within package will all be encoded into the binary returned.

The binary returned can be decoded to recover the WIT package provided.
