Struct Notes 

struct Notes {
    current: HashMap<String, (u64, Arc<AtomicBool>)>,
    shown: HashMap<String, i64>,
}

The latest spawn of each pane that carries the record, and when each pane last showed a note.

Fields

current: HashMap<String, (u64, Arc<AtomicBool>)>

block → (this spawn’s token, its “record not yet sent” flag). A newer spawn replaces the entry, so an older spawn’s task stands down: its flag belongs to a process that is gone, and the user may already have typed into the new one (#4707).

shown: HashMap<String, i64>

block → when its last note was shown.

Implementations

impl Notes

fn shown_recently(&self, block_id: &str, now: i64) -> bool

fn register( &mut self, block_id: &str, token: u64, pending: Arc<AtomicBool>, now: i64, ) -> bool

Records token as block_id’s latest spawn. False when a note was shown inside REPEAT_WINDOW_MS: no second note for the same switch.

fn still_wanted(&self, block_id: &str, token: u64) -> bool

Whether token is still block_id’s latest spawn and its record hasn’t gone out with a user message.

fn take_show(&mut self, block_id: &str, token: u64, now: i64) -> bool

Takes the right to show the note, once: token is still wanted and no note was shown inside the window.

Trait Implementations

impl Default for Notes

fn default() -> Notes

Returns the “default value” for a type.
