Struct WasmRefAccess

pub struct WasmRefAccess<'a, T>
where
    T: ValueType,
{
    pub(crate) is_owned: bool,
    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

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>, is_owned: bool, ) -> Result<Self, MemoryAccessError>

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

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

impl<T> WasmRefAccess<'_, T>

where T: ValueType,

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

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

Trait Implementations

impl<T> AsMut<T> for WasmRefAccess<'_, 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<T> AsRef<T> for WasmRefAccess<'_, T>

where T: ValueType,

fn as_ref(&self) -> &T

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

impl<T> Drop for WasmRefAccess<'_, T>

where T: ValueType,

fn drop(&mut self)

Executes the destructor for this type.
