Struct MutProxy

pub struct MutProxy<'a, T, W, E, B>
where
    T: Storable<W>,
    W: Word,
    E: Endianness,
    B: AsRef<[W]> + AsMut<[W]>,
{ /* private fields */ }

A proxy object for mutable access to an element within a FixedVec.

This struct is returned by FixedVec::at_mut. It holds a temporary copy of an element’s value. When the proxy is dropped, its Drop implementation writes the (potentially modified) value back into the parent vector. This “copy-on-read, write-on-drop” mechanism allows for an API that feels like direct mutable access.

Implementations

impl<'a, T, W, E, B> MutProxy<'a, T, W, E, B>

where T: Storable<W>, W: Word, E: Endianness, B: AsRef<[W]> + AsMut<[W]>,

pub fn into_inner(self) -> T

Consumes the proxy, returning the current value without writing it back.

This can be used to avoid the overhead of a write operation if the value was read but not modified.

Trait Implementations

impl<T, W, E, B> Deref for MutProxy<'_, T, W, E, B>

where T: Storable<W>, W: Word, E: Endianness, B: AsRef<[W]> + AsMut<[W]>,

fn deref(&self) -> &Self::Target

Returns a reference to the temporary value held by the proxy.

type Target = T

The resulting type after dereferencing.

impl<T, W, E, B> DerefMut for MutProxy<'_, T, W, E, B>

where T: Storable<W>, W: Word, E: Endianness, B: AsRef<[W]> + AsMut<[W]>,

fn deref_mut(&mut self) -> &mut Self::Target

Returns a mutable reference to the temporary value, allowing modification.

impl<T, W, E, B> Drop for MutProxy<'_, T, W, E, B>

where T: Storable<W>, W: Word, E: Endianness, B: AsRef<[W]> + AsMut<[W]>,

fn drop(&mut self)

Writes the potentially modified value back to the FixedVec when the proxy goes out of scope.
