Struct s2n_quic::provider::event::query::Once

pub struct Once<F, Context, Outcome> { /* private fields */ }

A type that implements Query and QueryMut traits and only executes once.

This will execute and short-circuit on the first match.

Implementations

impl<F, ConnectionContext, Outcome> Once<F, ConnectionContext, Outcome>

where F: FnOnce(&ConnectionContext) -> Outcome, ConnectionContext: 'static,

pub fn new(query: F) -> Once<F, ConnectionContext, Outcome>

impl<F, ConnectionContext, Outcome> Once<F, ConnectionContext, Outcome>

where F: FnOnce(&mut ConnectionContext) -> Outcome, ConnectionContext: 'static,

pub fn new_mut(query: F) -> Once<F, ConnectionContext, Outcome>

Trait Implementations

impl<F, Context, Outcome> From<Once<F, Context, Outcome>> for Result<Outcome, Error>

fn from(query: Once<F, Context, Outcome>) -> Result<Outcome, Error>

Converts to this type from the input type.

impl<F, Context, Outcome> Query for Once<F, Context, Outcome>

where F: FnOnce(&Context) -> Outcome, Context: 'static,

fn execute(&mut self, context: &(dyn Any + 'static)) -> ControlFlow

impl<F, Context, Outcome> QueryMut for Once<F, Context, Outcome>

where F: FnOnce(&mut Context) -> Outcome, Context: 'static,

fn execute_mut(&mut self, context: &mut (dyn Any + 'static)) -> ControlFlow
