A conflict detected while trying to construct an LR(1) parse table.

Variants

ReduceReduce

A reduce-reduce conflict.

Fields of ReduceReduce

state: ItemSet<'a, T, N, A>	The LR(0) state in which the conflict occurs.
token: Option<&'a T>	The token leading to the conflict, or None if the token is EOF.
r1: (&'a N, &'a Rhs<T, N, A>)	The first conflicting rule.
r2: (&'a N, &'a Rhs<T, N, A>)	The second conflicting rule.

ShiftReduce

A shift-reduce conflict.

Fields of ShiftReduce

state: ItemSet<'a, T, N, A>	The LR(0) state in which the conflict appears.
token: Option<&'a T>	The token leading to the conflict, or None if the token is EOF.
rule: (&'a N, &'a Rhs<T, N, A>)	The reduce rule involved in the conflict.
