Struct TextObjectContext 

pub struct TextObjectContext<'a> {
    pub buffer: &'a Buffer,
    pub at: Position,
    pub count: Count,
    pub args: Args,
    pub cancel: &'a CancellationToken,
    pub scope_resolver: Option<&'a dyn ScopeResolver>,
    pub comment_syntax: Option<&'a CommentSyntax>,
    pub path: Option<&'a Path>,
    pub syntax: Option<&'a Arc<dyn Any + Send + Sync>>,
}

Context passed to a text-object’s evaluator.

Fields

buffer: &'a Buffer

The buffer text the object reads.

at: Position

The cursor the object is evaluated around.

count: Count

The count, 1 when none was typed (2aw, 2i().

args: Args

The object’s own arguments.

cancel: &'a CancellationToken

Cooperative cancellation handle (DESIGN.md §5.2.5). Most text objects are O(line); polling rarely matters. Tag / paragraph / sentence objects that walk further can poll cancel.check()? on their inner loops.

scope_resolver: Option<&'a dyn ScopeResolver>

N.1.4a: tree-sitter scope resolver for the structural text objects (af / ac / …), injected by the host (backed by the buffer’s SyntaxSnapshot). None for buffers with no syntax — the structural objects then resolve nothing; the classic objects (iw, ap, i{) never read it.

comment_syntax: Option<&'a CommentSyntax>

N.1.6: comment-leader descriptor for the comment objects (aC / iC), injected by the host from the active buffer’s language. None (or line: None) ⇒ the comment objects resolve nothing. Only aC / iC read it.

path: Option<&'a Path>

OM.6b: the file the object’s buffer is backed by — the borrowed peer of MotionContext::path, for the same reason.

syntax: Option<&'a Arc<dyn Any + Send + Sync>>

OT.1: the type-erased tree-sitter snapshot — the borrowed peer of MotionContext::syntax, for the same reason, and carrying the same version-agreement guarantee.

Distinct from scope_resolver above rather than replacing it: the resolver answers “what scope encloses this point” for the native structural objects, while this hands a plugin the whole tree to query. A plugin object resolving a subtree needs the second, not the first.
