pub struct TimelineItem { /* private fields */ }
Expand description

A single entry in timeline.

Implementations§

source§

impl TimelineItem

source

pub fn kind(&self) -> &TimelineItemKind

Get the TimelineItemKind of this item.

source

pub fn as_event(&self) -> Option<&EventTimelineItem>

Get the inner EventTimelineItem, if this is a TimelineItemKind::Event.

source

pub fn as_virtual(&self) -> Option<&VirtualTimelineItem>

Get the inner VirtualTimelineItem, if this is a TimelineItemKind::Virtual.

source

pub fn unique_id(&self) -> &TimelineUniqueId

Get a unique ID for this timeline item.

It identifies the item on a best-effort basis. For instance, edits to an EventTimelineItem will not change the ID of the enclosing TimelineItem. For some virtual items like day dividers, identity isn’t easy to define though and you might see a new ID getting generated for a day divider that you perceive to be “the same” as a previous one.

source

pub fn is_day_divider(&self) -> bool

Check whether this item is a day divider.
