Enum ParserBackendSelection 

pub enum ParserBackendSelection {
    Backend(ParserBackend),
    ConflictsRequireGlr,
}

Contract outcome for backend selection under a given conflict condition.

This keeps behavior assertions in one place across parser and governance contracts without forcing callers to duplicate panic-string checks.

Variants

Backend(ParserBackend)

A concrete backend can be selected for the current feature set.

ConflictsRequireGlr

Conflict grammars require the glr feature to be enabled.

Trait Implementations

impl Clone for ParserBackendSelection

fn clone(&self) -> ParserBackendSelection

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ParserBackendSelection

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for ParserBackendSelection

fn eq(&self, other: &ParserBackendSelection) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
