Struct wasmtime_runtime::ModuleMemoryImages

pub struct ModuleMemoryImages { /* private fields */ }

Backing images for memories in a module.

This is meant to be built once, when a module is first loaded/constructed, and then used many times for instantiation.

Implementations

impl ModuleMemoryImages

pub fn get_memory_image( &self, defined_index: DefinedMemoryIndex ) -> Option<&Arc<MemoryImage>>

Get the MemoryImage for a given memory.

impl ModuleMemoryImages

pub fn new( module: &Module, wasm_data: &[u8], mmap: Option<&MmapVec> ) -> Result<Option<ModuleMemoryImages>>

Create a new ModuleMemoryImages for the given module. This can be passed in as part of a InstanceAllocationRequest to speed up instantiation and execution by using copy-on-write-backed memories.
