Methods

impl Module

pub fn new() -> Self

Allocates the module data structures.

pub fn func_index(&self, defined_func: DefinedFuncIndex) -> FuncIndex

Convert a DefinedFuncIndex into a FuncIndex.

pub fn defined_func_index(&self, func: FuncIndex) -> Option<DefinedFuncIndex>

Convert a FuncIndex into a DefinedFuncIndex. Returns None if the index is an imported function.

pub fn is_imported_function(&self, index: FuncIndex) -> bool

Test whether the given function index is for an imported function.

pub fn table_index(&self, defined_table: DefinedTableIndex) -> TableIndex

Convert a DefinedTableIndex into a TableIndex.

pub fn defined_table_index(
    &self,
    table: TableIndex
) -> Option<DefinedTableIndex>

Convert a TableIndex into a DefinedTableIndex. Returns None if the index is an imported table.

pub fn is_imported_table(&self, index: TableIndex) -> bool

Test whether the given table index is for an imported table.

pub fn memory_index(&self, defined_memory: DefinedMemoryIndex) -> MemoryIndex

Convert a DefinedMemoryIndex into a MemoryIndex.

pub fn defined_memory_index(
    &self,
    memory: MemoryIndex
) -> Option<DefinedMemoryIndex>

Convert a MemoryIndex into a DefinedMemoryIndex. Returns None if the index is an imported memory.

pub fn is_imported_memory(&self, index: MemoryIndex) -> bool

Test whether the given memory index is for an imported memory.

pub fn global_index(&self, defined_global: DefinedGlobalIndex) -> GlobalIndex

Convert a DefinedGlobalIndex into a GlobalIndex.

pub fn defined_global_index(
    &self,
    global: GlobalIndex
) -> Option<DefinedGlobalIndex>

Convert a GlobalIndex into a DefinedGlobalIndex. Returns None if the index is an imported global.

pub fn is_imported_global(&self, index: GlobalIndex) -> bool

Test whether the given global index is for an imported global.

pub fn hash_for_cache<'data, H>(
    &self,
    function_body_inputs: &PrimaryMap<DefinedFuncIndex, FunctionBodyData<'data>>,
    state: &mut H
) where
    H: Hasher, 

Computes hash of the module for the purpose of caching.

Trait Implementations

impl Debug for Module

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

Formats the value using the given formatter.
