Struct MultiConstraint 

pub struct MultiConstraint { /* private fields */ }

A compound constraint combining multiple constraints with AND or OR.

Implementations

impl MultiConstraint

pub fn new(constraints: Vec<Box<dyn Constraint>>, conjunctive: bool) -> Self

Create a new multi-constraint. conjunctive = true means AND (all must match), false means OR (any must match).

pub fn create( constraints: Vec<Box<dyn Constraint>>, conjunctive: bool, ) -> Box<dyn Constraint>

Smart constructor that optimizes and handles edge cases. Returns appropriate type: MatchAll, MatchNone, Single, or Multi.

Panics

Never panics - the unwrap is only reached when length is exactly 1.

pub const fn is_conjunctive(&self) -> bool

Check if this is a conjunctive (AND) constraint.

pub const fn is_disjunctive(&self) -> bool

Check if this is a disjunctive (OR) constraint.

pub fn constraints(&self) -> &[Box<dyn Constraint>]

Get the inner constraints.
