Struct ParserConfig 

pub struct ParserConfig { /* private fields */ }

Controls optional parser behavior beyond core AST construction.

Keep defaults for pure parsing. Enable extras only when your tool needs them (for example, token-level highlighting or parser debugging).

Implementations

impl ParserConfig

pub fn trace(&self) -> bool

Whether parser debug trace logging is enabled. Default: false.

Useful when debugging grammar behavior; usually disabled in production.

pub fn collect_tokens(&self) -> bool

Whether parser tokens/comments are recorded for each statement. Default: false.

Enable this for tooling that needs precise token streams (formatters, diagnostics, semantic highlighting).

pub fn with_trace(self, trace: bool) -> Self

Enable or disable parser trace logging.

pub fn with_collect_tokens(self, collect_tokens: bool) -> Self

Enable or disable token/comment capture on parse results.

pub fn macro_fallback(&self) -> bool

Whether macro fallback is enabled. Default: false.

When enabled and the dialect uses Rust-style macros, unregistered name!(args) calls are consumed as a single TK_ID token instead of causing a parse error. A MacroRegion is recorded so the formatter can emit the call verbatim.

pub fn with_macro_fallback(self, macro_fallback: bool) -> Self

Enable or disable macro fallback for unregistered macro calls.
