Struct Cardinality 

pub struct Cardinality {
    pub min: u32,
    pub max: Option<u32>,
}

How many values a parameter takes.

Fields

min: u32

The minimum number of values.

max: Option<u32>

The maximum number of values; None is unbounded (*).

Implementations

impl Cardinality

pub const fn admits(self, count: u32) -> bool

Whether count values satisfy this cardinality.
