[−][src]Struct wasmer_runtime::Ctx

#[repr(C)]

pub struct Ctx {
    pub data: *mut c_void,
    pub data_finalizer: Option<fn(*mut c_void)>,
    // some fields omitted
}

The context of the currently running WebAssembly instance.

Fields

data: *mut c_voiddata_finalizer: Option<fn(*mut c_void)>

Methods

impl Ctx[src]

pub fn memory(&self, mem_index: u32) -> &Memory[src]

This exposes the specified memory of the WebAssembly instance as a immutable slice.

WebAssembly will soon support multiple linear memories, so this forces the user to specify.

Usage:

fn read_memory(ctx: &Ctx) -> u8 {
    let first_memory = ctx.memory(0);
    // Read the first byte of that linear memory.
    first_memory.view()[0].get()
}

pub unsafe fn borrow_symbol_map(
    &self
) -> &Option<HashMap<u32, String, BuildHasherDefault<FxHasher>>>[src]

Gives access to the emscripten symbol map, used for debugging
