Struct wasmparser_nostd::FuncToValidate

pub struct FuncToValidate<T> {
    pub resources: T,
    pub index: u32,
    pub ty: u32,
    pub features: WasmFeatures,
}

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.

Fields

resources: T

The reusable heap allocated resources required for Wasm validation.

index: u32

The function index within the Wasm module.

ty: u32

The type index of the function.

features: WasmFeatures

The Wasm features used for validating the function.

Implementations

impl<T: WasmModuleResources> FuncToValidate<T>

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.
