Low-level WebAssembly parser, with a focus on zero allocations.

Designed to allow easier processing of a WebAssembly module's sections in parallel.

The following WebAssembly proposals are fully supported by the parser:

• Merged (Phase 5) Proposals:
  • Mutable Globals
  • Non-Trapping Float-to-Integer Conversions
  • Sign Extension Operators
  • Multi-Value
  • Reference Types
  • Bulk Memory Operations
  • Fixed Width SIMD
• Phase 4 Proposals:
  • Tail Call
  • Extended Constant Expressions
• Phase 3 Proposals:
  • Multi-Memory
  • Memory64
  • Exception Handling
  • Threads

This library is completely #![no_std] compatible, capable of being used with or without the alloc library. The std and alloc features control this.
