Struct wasmer::access::WasmRefAccess

pub struct WasmRefAccess<'a, T>where
    T: ValueType,{
    pub(crate) ptr: WasmRef<'a, T>,
    pub(crate) buf: RefCow<'a, T>,
}

Provides direct memory access to a piece of memory that is owned by WASM

Fields

ptr: WasmRef<'a, T>

buf: RefCow<'a, T>

Implementations

impl<'a, T> WasmRefAccess<'a, T>where T: ValueType,

pub fn as_mut_uninit(&mut self) -> &mut MaybeUninit<T>

Returns a reference to an unitialized reference to this value

impl<'a, T> WasmRefAccess<'a, T>where T: ValueType,

pub(crate) fn new(ptr: WasmRef<'a, T>) -> Result<Self, MemoryAccessError>

impl<'a, T> WasmRefAccess<'a, T>where T: ValueType,

pub fn read(&self) -> Twhere T: Clone,

Reads the address pointed to by this WasmPtr in a memory.

pub fn write(&mut self, val: T)

Writes to the address pointed to by this WasmPtr in a memory.

Trait Implementations

impl<'a, T> AsMut<T> for WasmRefAccess<'a, T>where T: ValueType,

fn as_mut(&mut self) -> &mut T

Converts this type into a mutable reference of the (usually inferred) input type.

impl<'a, T> AsRef<T> for WasmRefAccess<'a, T>where T: ValueType,

fn as_ref(&self) -> &T

Converts this type into a shared reference of the (usually inferred) input type.

impl<'a, T> Drop for WasmRefAccess<'a, T>where T: ValueType,

fn drop(&mut self)

Executes the destructor for this type.
