Implementations

impl<Q: QueryContext> PatternDefinition<Q>

pub fn new( name: String, scope: usize, params: Vec<(String, Variable)>, pattern: Pattern<Q>, ) -> Self

pub fn new_ephemeral( params: Vec<(String, Variable)>, pattern: Pattern<Q>, ) -> Self

Create an unnamed ephemeral pattern This is primarily useful for the bubble pattern, where we want to create a new scope

pub fn try_scope(&self) -> GritResult<usize>

pub fn replace_pattern(&mut self, new_pattern: Pattern<Q>)

pub fn params(&self) -> &Vec<(String, Variable)>

pub fn pattern(&self) -> &Pattern<Q>
