Struct wasmtime_environ::wasmparser::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

Reusable, heap allocated resources to drive the Wasm validation.

index: u32

The core Wasm function index being validated.

ty: u32

The core Wasm type index of the function being validated, defining the results and parameters to the function.

features: WasmFeatures

The Wasm features enabled to validate the function.

Implementations

impl<T> FuncToValidate<T>

where T: WasmModuleResources,

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.

Trait Implementations

impl<T> Debug for FuncToValidate<T>

where T: Debug,

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.
