Struct wasmtime_environ::wasmparser::FuncToValidate

source ·
pub struct FuncToValidate<T> { /* private fields */ }
Expand description

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§

source§

impl<T> FuncToValidate<T>

source

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.
source

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.
