Struct chronicle::queue::TailerDirection

#[repr(transparent)]
pub struct TailerDirection {
    pub repr: u8,
}

The default action for a tailer after reading a message is to advance forwards to the next (higher) message. The TailerDirection allows the direction of movement to be controlled, and the options are:

• None: don’t advance the read position
• Forward: advance the read position forwards to the next (higher) message
• Backward: advance the read position backwards to the previous (lower) message

Fields

repr: u8

Trait Implementations

impl Clone for TailerDirection

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl ExternType for TailerDirection

type Kind = Trivial

Either cxx::kind::Opaque or cxx::kind::Trivial.

type Id

A type-level representation of the type’s C++ namespace and type name.

impl PartialEq<TailerDirection> for TailerDirection

fn eq(&self, other: &TailerDirection) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
