Crate wit_text

A crate to parse the textual format for WebAssembly interface types.

This crate is a work-in-progress and should expect to have a good deal of change as the official proposal evolves. The main purpose of this crate is to parse a textual file into a binary representation, and the parsing includes parsing of all of the WebAssembly core types/syntax as well.

Structs

Export	An exported wasm interface types function
Func	A definition of an adapter function
Implement	A means of implementing a core wasm imported function with an adapter function.
Import	An imported function declaration using wasm interface types.
Instructions	A list of instructions, possibly in s-expression form
MemoryToString	Payload of the memory-to-string instruction
Module	A WebAssembly interface types-enhanced module.
StringToMemory	Payload of the string-to-memory instruction
Type	A type declaration in a wasm interface type subsection
TypeUse	An inline type definition or a use of a type defined elsewhere.
Wit	A *.wit file in its entirety.

Enums

Adapter	List of possible @interface adapters that can be listed in a module.
FuncKind	Different flavors of functions that can be defined.
Implementation	Different ways to specify an implementation
Implemented	Different ways to specify what's being implemented
Instruction	List of instructions in adapter functions.
ValType	Possible value types that can be used in function signatures and such.

Functions

parse_file	Parses a file on the filesystem as a textual representation of WebAssembly Interface Types, returning the binary representation of the module.
parse_str	Parses an in-memory string as the textual representation of WebAssembly interface types and returned the binary serialization of the module.
