Enum LiveBackPaginationStatus

pub enum LiveBackPaginationStatus {
    Idle {
        hit_start_of_timeline: bool,
    },
    Paginating,
}

Status for the back-pagination on a live timeline.

Variants

Idle

No back-pagination is happening right now.

Fields

hit_start_of_timeline: bool

Have we hit the start of the timeline, i.e. back-paginating wouldn’t have any effect?

Paginating

Back-pagination is already running in the background.

impl PartialEq for LiveBackPaginationStatus

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

Tests for self and other values to be equal, and is used by ==.

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

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