Struct ModuleTables

pub struct ModuleTables<'a> { /* private fields */ }

Tables Section of a module

Implementations

impl<'a> ModuleTables<'a>

pub fn new(tables: Vec<(TableType, Option<ConstExpr<'a>>)>) -> Self

Create a new table section

pub fn is_empty(&self) -> bool

Check if there are any tables

pub fn iter(&self) -> Iter<'_, (TableType, Option<ConstExpr<'a>>)>

Create an iterable over the table section

pub fn main_function(&self) -> Option<TableID>

Finds a unique function table in a module.

Modules produced by compilers like LLVM typically have one function table for indirect function calls. This function will look for a single function table inside this module, and return that if found. If no function tables are present None will be returned

Errors

Returns an error if there are two function tables in this module

Inspired from walrus’ implementation

pub fn get(&self, table_id: TableID) -> Option<TableType>

Get a table

pub fn get_mut(&mut self, table_id: TableID) -> &mut TableType

Get a mutable reference to a table

Trait Implementations

impl<'a> Clone for ModuleTables<'a>

fn clone(&self) -> ModuleTables<'a>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for ModuleTables<'a>

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

Formats the value using the given formatter.

impl<'a> Default for ModuleTables<'a>

fn default() -> ModuleTables<'a>

Returns the “default value” for a type.
