TutorHeaderlineState

lattice_host::tutor::mode

Struct TutorHeaderlineState 

Source 
pub struct TutorHeaderlineState(pub SimpleHeaderlineHandle<TutorViewState>);
Expand description

Buffer-local handle for updating the tutor headerline. Wraps a SimpleHeaderlineHandle<TutorViewState> so dispatch can push session state without holding a reference to the provider itself.

Trait Implementations§

Source§

impl BufferLocal for TutorHeaderlineState

Source§

const NAME: &'static str = "tutor-mode.headerline"

Public display name (:describe-buffer row label, debug logs). Convention: <owner-mode-name>.<key>, e.g. "file-tree.entries". Not a registry key — locals aren’t registered globally; the name is metadata for inspection.
Source§

const DOC: &'static str = "SimpleHeaderlineHandle for the tutor buffer's sticky HUD row."

Doc string. Shown in :describe-buffer when the user expands a local for detail.
Source§

const OWNER_MODE: &'static str = "tutor-mode"

Mode id that owns this local. Attribution metadata for :describe-buffer; the write-time check the design calls for (a ModeContext::set_local::<T> that rejects a non-owner) is not implemented, so nothing enforces it today (see the module docs).
Source§

fn describe(&self) -> String

Single-line summary of the local’s value for :describe-buffer’s tabular display. Implementations should be cheap (no heavy formatting); detailed inspection is via the mode’s own commands.
Source§

fn clone(&self) -> TutorHeaderlineState

Returns a duplicate of the value. Read more
