This library provides all the types and traits necessary to use WebAssembly easily anywhere.

Among other things, it defines the following types:

  • units like Pages or Bytes
  • types and values like I32, I64, F32, F64, ExternRef, FuncRef, V128, value conversions, ExternType, FunctionType etc.
  • native contains a set of trait and implementations to deal with WebAssembly types that have a direct representation on the host,
  • memory_view, an API to read/write memories when bytes are interpreted as particular types (i8, i16, i32 etc.)
  • indexes contains all the possible WebAssembly module indexes for various types
  • initializers for tables, data etc.
  • features to enable or disable some WebAssembly features inside the Wasmer runtime

Acknowledgments

This project borrowed some of the code for the entity structure from cranelift-entity. We decided to move it here to help on serialization/deserialization.
