Enum cfg_expr::expr::Func[][src]

pub enum Func {
    Not,
    All(usize),
    Any(usize),
}
Expand description

A predicate function, used to combine 1 or more predicates into a single value

Variants

Not

not() with a configuration predicate. It is true if its predicate is false and false if its predicate is true.

All

all() with a comma separated list of configuration predicates. It is false if at least one predicate is false. If there are no predicates, it is true.

The associated usize is the number of predicates inside the all().

Tuple Fields of All

0: usize
Any

any() with a comma separated list of configuration predicates. It is true if at least one predicate is true. If there are no predicates, it is false.

The associated usize is the number of predicates inside the any().

Tuple Fields of Any

0: usize
