Implementations§

impl PreStartupExternalMessage

pub const fn event(&self) -> Event

Returns the protocol event represented by this message.

pub fn into_wire(self) -> PreStartupMessage

Returns the underlying decoded wire message.

Trait Implementations§

impl AsRef<PreStartupMessage> for PreStartupExternalMessage

fn as_ref(&self) -> &PreStartupMessage

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

fn from(message: PreStartupExternalMessage) -> Self

Converts to this type from the input type.

impl TryFrom<PreStartupMessage> for PreStartupExternalMessage

type Error = PreStartupMessage

The type returned in the event of a conversion error.

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

Performs the conversion.

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
