WebAssembly module

Fields

custom_sections: HashMap<&'a str, &'a [u8]>

Map the custom section name to its data.

start_section: Option<u32>

Start section function.

function_sections: Vec<u32>

Map the function index to the type index.

type_sections: Vec<FuncType>

Type sections containing functions only.

import_sections: Vec<Import<'a>>

Import sections.

code_sections: Vec<Vec<Operator<'a>>>

Code sections containing instructions only.

Implementations

impl<'a> Module<'a>

pub fn new(code: &'a [u8]) -> Result<Self>

Create a Module from the Wasm code.

pub fn has_function_name(&self, name: &str) -> Result<bool>

Check if the function name is present in the ‘name’ custom section.

pub fn function_type_index(&self, function: &FuncType) -> Option<usize>

Get the function’s type index from the type section.

pub fn function_import_index(&self, name: &str) -> Option<usize>

Get the function index from the import section.

pub fn functions_by_type( &self, function_type: &FuncType, ) -> Result<Vec<Vec<Operator<'_>>>>

Search for a functions in a WebAssembly (Wasm) module that matches a given function type.

If one or more functions matching the specified type are found, this function returns their bodies in a vector; otherwise, it returns an error.

Trait Implementations

impl<'a> Default for Module<'a>

fn default() -> Module<'a>

Returns the “default value” for a type.
