Expand description

A trait implemented by parser debuggers.

Required Methods§

source

fn scope<R, Info: FnOnce() -> ParserInfo, F: FnOnce(&mut Self) -> R>( &mut self, info: Info, f: F ) -> R

👎Deprecated: This trait is excluded from the semver guarantees of chumsky. If you decide to use it, broken builds are your fault.

Create a new debugging scope.

source

fn emit_with<F: FnOnce() -> ParseEvent>(&mut self, f: F)

👎Deprecated: This trait is excluded from the semver guarantees of chumsky. If you decide to use it, broken builds are your fault.

Emit a parse event, if the debugger supports them.
