Struct MessageOrderKey 

pub struct MessageOrderKey {
    pub time: SystemTime,
    pub id: MessageId,
}

The total order MessagesV1::apply_delta retains by: it sorts ascending on (time, id) and keeps the newest max_recent_messages, so this key alone decides whether a message survives a merge.

id breaks ties deterministically; without it two messages sharing a timestamp would order differently on different peers.

Fields

time: SystemTime

id: MessageId

Trait Implementations

impl Eq for MessageOrderKey

impl Ord for MessageOrderKey

fn cmp(&self, other: &MessageOrderKey) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,
