Implementations

impl CursorChats

pub fn say( &mut self, user: &UserId, said: Option<(&str, bool)>, now: Instant, ) -> bool

user says text beside their pointer (sent once they pressed Enter), or stops saying anything with None. Returns whether what is shown changed.

pub fn react( &mut self, user: &UserId, seq: u32, emoji: &str, now: Instant, ) -> bool

user reacted with emoji, their seqth reaction. Plays once per new counter; returns whether it started.

pub fn forget(&mut self, user: &UserId) -> bool

Forget everything user said and reacted: they left, or are no longer shown to this person.

pub fn bubble( &self, user: &UserId, now: Instant, motion: EffectiveMotion, ) -> Option<ChatBubble>

The bubble to draw beside user’s pointer at now.

pub fn reaction( &self, user: &UserId, now: Instant, motion: EffectiveMotion, ) -> Option<ReactionFloat>

The reaction to draw rising from user’s pointer at now.

pub fn talking(&self, user: &UserId, now: Instant) -> bool

Whether user is saying something at now: their pointer stays and keeps its name while they do.

pub fn prune(&mut self, now: Instant) -> bool

Drop messages that have lingered and reactions that are over. Returns whether anything went.

pub fn animating(&self, now: Instant) -> bool

Whether anything is arriving, fading or floating at now, so the painter needs another frame. Asks no more of the motion than the slowest it can be: a host without the person’s motion settings may paint a frame too many, never one too few.

pub fn next_change( &self, now: Instant, motion: EffectiveMotion, ) -> Option<Instant>

When the next change after now happens on its own (a sent message starts to fade), for a host that sleeps between frames.
