Types that qualify as Wasm valiation database.

Note

The wasmparser crate provides a builtin validation framework but allows users of this crate to also feed the parsed Wasm into their own data structure while parsing and also validate at the same time without the need of an additional parsing or validation step or copying data around.

Associated Types

type FuncType: WasmFuncType

The function type used for validation.
