Struct ExprId 

Source 
pub struct ExprId(pub u32);
Expand description

T3.4 (R2.4): a node’s identity, independent of position — allocated once, monotonically, per expression the parser constructs (Parser::alloc_expr_id in bynk-syntax/src/parser.rs). Never derived from a Span, so two expressions occupying the same byte range (a synthetic node, a zero-width span) never collide the way a span-keyed side table could.

Implementations§

Source§

impl ExprId

Source

pub const SYNTHETIC: ExprId

Reserved for Expr nodes built outside the parser — after checking, during emission — that are never looked up in a checker-populated expr_types/expr_ty table (they are lowered directly, from already-typed sub-expressions they wrap or splice). A lookup against this id is a bug: the node was never checked and has no recorded type of its own.

painted.fg(Color::White);

Set foreground color to white using white().

fn attr(&self, value: Attribute) -> Painted<&T>

Enables the styling [Attribute] value.

§

fn quirk(&self, value: Quirk) -> Painted<&T>
