Enum FieldMut 

pub enum FieldMut<'a, T: HasView<V>, V> {
    Repr(&'a mut T),
    Raw(&'a mut <T as HasView<V>>::ViewType),
}

An equivalent to Header for header fields which are accessed by mutable reference.

Variants

Repr(&'a mut T)

Mutable reference to the owned representation of a field.

Raw(&'a mut <T as HasView<V>>::ViewType)

Mutable reference to a field in a borrowed header, which may be owned or borrowed depdendent on past modifications.

Trait Implementations

impl<T: HasView<V, ViewType = Q> + AsMut<[u8]>, V, Q: AsMut<[u8]>> AsMut<[u8]> for FieldMut<'_, T, V>

fn as_mut(&mut self) -> &mut [u8]

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

impl<T: HasView<V, ViewType = Q> + AsRef<[u8]>, V, Q: AsRef<[u8]>> AsRef<[u8]> for FieldMut<'_, T, V>

fn as_ref(&self) -> &[u8]

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

impl<'a, T: HasView<V>, V> From<&'a mut BoxedHeader<T, <T as HasView<V>>::ViewType>> for FieldMut<'a, T, V>

Available on crate feature alloc only.

fn from(value: &'a mut BoxedHeader<T, <T as HasView<V>>::ViewType>) -> Self

Converts to this type from the input type.

impl<'a, T: HasView<V>, V> From<&'a mut InlineHeader<T, <T as HasView<V>>::ViewType>> for FieldMut<'a, T, V>

fn from(value: &'a mut InlineHeader<T, <T as HasView<V>>::ViewType>) -> Self

Converts to this type from the input type.

impl<T: HeaderLen + HasView<V>, V> HeaderLen for FieldMut<'_, T, V>

where T::ViewType: HeaderLen,

const MINIMUM_LENGTH: usize = T::MINIMUM_LENGTH

The minimum number of bytes a packet of this kind occupies when serialised.

fn packet_length(&self) -> usize

The number of bytes which this packet would occupy when serialised.

impl<T: HasView<V, ViewType = Q> + NextLayer, V, Q> NextLayer for FieldMut<'_, T, V>

where <T as HasView<V>>::ViewType: NextLayer<Denom = T::Denom, Hint = T::Hint>,

type Denom = <T as NextLayer>::Denom

The type of this header’s next-layer hint.

type Hint = <T as NextLayer>::Hint

A type used to help parse the header

fn next_layer_choice(&self, hint: Option<Self::Hint>) -> Option<Self::Denom>

Try to retrieve this header’s next-layer hint, using a provided hint

fn next_layer(&self) -> Option<Self::Denom>

Retrieve this header’s next-layer hint, if possible.
