Struct DocumentSyntax 

Source 
pub struct DocumentSyntax(pub Option<SyntaxHandle>);
Expand description

Per-document tree-sitter syntax handle. Some once a language has been detected for the buffer and a parse has been requested; None for Lang::Plain documents and for buffers that haven’t been activated yet.

Trait Implementations§

Source§

impl BufferLocal for DocumentSyntax

Source§

const NAME: &'static str = "text-mode.syntax"

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 = "Per-document tree-sitter syntax handle. Drives the highlight \ walk + the fold computation. Owned by the document's active \ language major (text-mode for `Lang::Plain`, the matching \ language mode otherwise); the handle's runtime data lives in \ a worker actor referenced by this slot."

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

const OWNER_MODE: &'static str = "text-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.
