Struct FollowState 

pub struct FollowState(/* private fields */);

Whether a follow view is still pinned, and the overflow it last saw.

Shaped like ScrollbarState and for the same reason: it mutates through &self, so the element carries the whole behaviour without the view wiring a listener. Starts pinned — a transcript or a log opens on its newest line.

Implementations

impl FollowState

pub fn new() -> Self

pub fn following(&self) -> bool

Whether the view is following. An app shows its “jump to latest” affordance on !following(), which is the only reason this is public.

pub fn follow(&self)

Re-pin. What that “jump to latest” button calls; the next frame does the scrolling.
