impl Trivia

Source

pub const fn comment_text(&self) -> Option<&str>

Project the wrapped TriviaKind::LineComment body as &str, or None on the sibling two arms (TriviaKind::BlankLine + TriviaKind::Shebang) — the trivia-envelope-scoped surface every downstream authoring consumer that only needs the line-comment body (a caixa-fmt block-comment paragraph-fill pass over the collected trivia list, a caixa-lint doc-comment / rustdoc-shape probe, a deferred caixa-lsp hover pop-up that renders the comment body on mouse-over) partitions on.

pub const fn — closes const-eval discipline on the Trivia envelope-scoped projection axis, peer with the sibling crate::TriviaKind IsVariant-derived per-arm predicate discriminators (TriviaKind::is_line_comment + TriviaKind::is_blank_line + TriviaKind::is_shebang) on the same trivia-arm-discriminator surface. The body reaches for String::as_str on the TriviaKind::LineComment borrowed- String slot — const-stable since Rust 1.87, well before this workspace’s 1.89 MSRV floor — so the promotion is a body-preserving type-signature widening. Matches the sibling per-source-position- primitive const-eval-surface family on the caixa-ast surface (crate::Span::new / crate::Span::point / crate::Span::len / crate::Span::is_empty / crate::Span::contains / crate::Span::union on the byte-offset axis, crate::Position::new / crate::Position::origin on the 1- indexed line/column axis, [crate::Position::line_column] on the Position projection axis, crate::NodeKind::seq_delims / crate::NodeKind::reader_macro_prefix / crate::NodeKind::as_keyword / crate::NodeKind::as_symbol / crate::NodeKind::as_str on the outer-NodeKind writer-half projection axis) — every downstream consumer that wants a compile-time line-comment-body fixture (a const HEADER: Option<&str> = TRIVIA.comment_text(); compile-time oracle a caixa-fmt paragraph-fill pass keys off, a per-lint const- context doc-comment shape probe a future admission webhook consults) now reads through one substrate-primitive const dispatch rather than being forced onto the runtime code path.
