Enum streamson_lib::matcher::combinator::Combinator

pub enum Combinator {
    Matcher(Arc<dyn MatchMaker + Sync>),
    Not(Box<Combinator>),
    And(Box<Combinator>, Box<Combinator>),
    Or(Box<Combinator>, Box<Combinator>),
}

Combines several matches together

It implements normal boolean algebra

• ! comb will negate the combinator
• comb1 & comb2 both should pass
• comb1 | comb2 at least one should pass

Variants

Matcher(Arc<dyn MatchMaker + Sync>)

Represents the actual underlying matcher

Not(Box<Combinator>)

Negates the expression

And(Box<Combinator>, Box<Combinator>)

Both expressions should be valid

Or(Box<Combinator>, Box<Combinator>)

At least one of the expressions should be valid
