A WebAssembly binary parser in WebAssembly. Super small, super fast, with TypeScript support.
API
---
* **parse**(binary: `Uint8Array`, options?: `ParseOptions`): `void`
Parses the contents of a WebAssembly binary according to the specified options.
* **ParseOptions**
Options specified to the parser. The `onSection` callback determines the sections being evaluated in detail.
* **onSection**?(id: `SectionId`, payloadOff: `number`, payloadLen: `number`, nameOff: `number`, nameLen: `number`): `boolean`
Called with each section in the binary. Returning `true` evaluates the section.
* **onType**?(index: `number`, form: `number`): `void`
Called with each function type if the type section is evaluated.
* **onTypeParam**?(index: `number`, paramIndex: `number`, paramType: `Type`): `void`
Called with each function parameter if the type section is evaluated.
* **onTypeReturn**?(index: `number`, returnIndex: `number`, returnType: `Type`): `void`
Called with each function return type if the type section is evaluated.
* **onImport**?(index: `number`, kind: `ExternalKind`, moduleOff: `number`, moduleLen: `number`, fieldOff: `number`, fieldLen: `number`): `void`
Called with each import if the import section is evaluated.
* **onFunctionImport**?(index: `number`, type: `number`): `void`
Called with each function import if the import section is evaluated.
* **onTableImport**?(index: `number`, type: `Type`, initial: `number`, maximum: `number`, flags: `number`): `void`
Called with each table import if the import section is evaluated.
* **onMemoryImport**?(index: `number`, initial: `number`, maximum: `number`, flags: `number`): `void`
Called with each memory import if the import section is evaluated.
* **onGlobalImport**?(index: `number`, type: `Type`, mutability: `number`): `void`
Called with each global import if the import section is evaluated.
* **onMemory**?(index: `number`, initial: `number`, maximum: `number`, flags: `number`): `void`
Called with each memory if the memory section is evaluated.
* **onFunction**?(index: `number`, typeIndex: `number`): `void`
Called with each function if the function section is evaluated.
* **onGlobal**?(index: `number`, type: `Type`, mutability: `number`): `void`
Called with each global if the global section is evaluated.
* **onStart**?(index: `number`): `void`
Called with the start function index if the start section is evaluated.
* **onExport**?(index: `number`, kind: `ExternalKind`, kindIndex: `number`, nameOff: `number`, nameLen: `number`): `void`
Called with each export if the export section is evaluated.
* **onSourceMappingURL**?(offset: `number`, length: `number`): `void`
Called with the source map URL if the 'sourceMappingURL' section is evaluated.
* **onModuleName**?(offset: `number`, length: `number`): `void`
Called with the module name if present and the 'name' section is evaluated.
* **onFunctionName**?(index: `number`, offset: `number`, length: `number`): `void`
Called with each function name if present and the 'name' section is evaluated.
* **onLocalName**?(funcIndex: `number`, index: `number`, offset: `number`, length: `number`): `void`
Called with each local name if present and the 'name' section is evaluated.
* **Type**
A value or element type, depending on context.
