Struct wasmtime_environ::wasmparser::FuncToValidate

pub struct FuncToValidate<T> { /* private fields */ }

Resources necessary to perform validation of a function.

This structure is created by Validator::code_section_entry and is created per-function in a WebAssembly module. This structure is suitable for sending to other threads while the original Validator continues processing other functions.

Implementations

impl<T> FuncToValidate<T>where
    T: WasmModuleResources,

pub fn new(
    index: u32,
    ty: u32,
    resources: T,
    features: &WasmFeatures
) -> FuncToValidate<T>

Creates a new function to validate which will have the specified configuration parameters:

• index - the core wasm function index being validated
• ty - the core wasm type index of the function being validated, defining the results and parameters to the function.
• resources - metadata and type information about the module that this function is validated within.
• features - enabled WebAssembly features.

pub fn into_validator(self, allocs: FuncValidatorAllocations) -> FuncValidator<T>

Converts this FuncToValidate into a FuncValidator using the allocs provided.

This method, in conjunction with FuncValidator::into_allocations, provides a means to reuse allocations across validation of each individual function. Note that it is also sufficient to call this method with Default::default() if no prior allocations are available.

Panics

If a FuncToValidate was created with an invalid ty index then this function will panic.
