Crate wasmparser
source ·Expand description
A simple event-driven library for parsing WebAssembly binary files (or streams).
The parser library reports events as they happend and only stores parsing information for a brief period of time, making it very fast and memory-efficient. The event-driven model, however, has some drawbacks. If you need random access to the entire WebAssembly data-structure, this is not the right library for you. You could however, build such a data-structure using this library.
Structs
- A binary reader of the WebAssembly structures and types.
- A br_table entries representation.
- Validation context for a WebAssembly function.
- An IEEE binary32 immediate floating point value, represented as a u32 containing the bitpattern.
- An IEEE binary64 immediate floating point value, represented as a u64 containing the bitpattern.
- An incremental parser of a binary WebAssembly module.
- Bytecode range in the WebAssembly module.
- Validator for a WebAssembly binary module.
- The implementation of
WasmModuleResourcesused byValidator. - Flags for features that are enabled for validation.
- Iterator over the inputs of a Wasm function type.
- Iterator over the outputs of a Wasm function type.
Enums
- A successful return payload from
Parser::parse. - External types as defined here.
- Instructions as defined here.
- Values that can be parsed from a wasm module.
- Section code as defined here.
- Types as defined here.
- Either a value type or a function type.
- Possible return values from
Validator::payload.
Traits
- Types that qualify as Wasm function types for validation purposes.
- Types that qualify as Wasm valiation database.
Functions
- Test whether the given buffer contains a valid WebAssembly module, analogous to
WebAssembly.validatein the JS API.
