[−][src]Struct wasmer_vm::Imports

pub struct Imports {
    pub functions: BoxedSlice<FunctionIndex, VMFunctionImport>,
    pub host_function_env_initializers: Option<BoxedSlice<FunctionIndex, (Option<ImportInitializerFuncPtr>, *mut c_void)>>,
    pub tables: BoxedSlice<TableIndex, VMTableImport>,
    pub memories: BoxedSlice<MemoryIndex, VMMemoryImport>,
    pub globals: BoxedSlice<GlobalIndex, VMGlobalImport>,
}

Resolved import pointers.

Fields

functions: BoxedSlice<FunctionIndex, VMFunctionImport>

Resolved addresses for imported functions.

host_function_env_initializers: Option<BoxedSlice<FunctionIndex, (Option<ImportInitializerFuncPtr>, *mut c_void)>>

Initializers for host function environments. This is split out from functions because the generated code never needs to touch this and the extra wasted space may affect Wasm runtime performance due to increased cache pressure.

We make it optional so that we can free the data after use.

tables: BoxedSlice<TableIndex, VMTableImport>

Resolved addresses for imported tables.

memories: BoxedSlice<MemoryIndex, VMMemoryImport>

Resolved addresses for imported memories.

globals: BoxedSlice<GlobalIndex, VMGlobalImport>

Resolved addresses for imported globals.

Implementations

impl Imports[src]

pub fn new(
    function_imports: PrimaryMap<FunctionIndex, VMFunctionImport>,
    host_function_env_initializers: PrimaryMap<FunctionIndex, (Option<ImportInitializerFuncPtr>, *mut c_void)>,
    table_imports: PrimaryMap<TableIndex, VMTableImport>,
    memory_imports: PrimaryMap<MemoryIndex, VMMemoryImport>,
    global_imports: PrimaryMap<GlobalIndex, VMGlobalImport>
) -> Self[src]

Construct a new Imports instance.

pub fn none() -> Self[src]

Construct a new Imports instance with no imports.

pub fn get_import_initializers(
    &mut self
) -> Vec<(Option<ImportInitializerFuncPtr>, *mut c_void)>[src]

Get the WasmerEnv::init_with_instance function pointers and the pointers to the envs to call it on.

This function can only be called once, it deletes the data it returns after returning it to ensure that it's not called more than once.
