Implementations§

impl PreStartupInternalMessage

pub const fn event(&self) -> Event

Returns the protocol event represented by this message.

Returns the underlying decoded wire message.

Trait Implementations§

impl AsRef<PreStartupMessage> for PreStartupInternalMessage

fn as_ref(&self) -> &PreStartupMessage

fn from(message: PreStartupInternalMessage) -> Self

Converts to this type from the input type.

impl TryFrom<PreStartupMessage> for PreStartupInternalMessage

type Error = PreStartupMessage

The type returned in the event of a conversion error.

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

Performs the conversion.

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
