Implementations§

impl SimpleExternalMessage

pub const fn event(&self) -> Event

Returns the protocol event represented by this message.

pub const fn as_wire(&self) -> &BackendMessage

Borrows the underlying decoded wire message.

pub fn into_wire(self) -> BackendMessage

Returns the underlying decoded wire message.

Trait Implementations§

impl AsRef<BackendMessage> for SimpleExternalMessage

fn as_ref(&self) -> &BackendMessage

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

impl From<SimpleExternalMessage> for BackendMessage

fn from(message: SimpleExternalMessage) -> Self

Converts to this type from the input type.

impl TryFrom<BackendMessage> for SimpleExternalMessage

type Error = BackendMessage

The type returned in the event of a conversion error.

fn try_from(message: BackendMessage) -> Result<Self, BackendMessage>

Performs the conversion.

where T: 'a,

fn explicit(self, class: Class, tag: u32) -> TaggedParser<'a, Explicit, Self, E>

impl<'a, T, E> AsTaggedImplicit<'a, E> for T
where T: 'a,

impl<T> From<T> for T

fn from(t: T) -> T

impl<T, U> TryFrom<U> for T
where U: Into<T>,

type Error = Infallible

The type returned in the event of a conversion error.

fn try_from(value: U) -> Result<T, <T as TryFrom<U>>::Error>

Performs the conversion.

impl<T, U> TryInto<U> for T
where U: TryFrom<T>,

type Error = <U as TryFrom<T>>::Error
