Enum LengthConstraint 

pub enum LengthConstraint {
    Exact(usize),
    AtLeast(usize),
    AtMost(usize),
    InRange {
        min: usize,
        max: usize,
    },
}

A numeric relationship required of a measured string or collection length.

LengthMetric identifies the measurement unit in a structured validation error.

Variants

Exact(usize)

Requires exactly the specified length.

AtLeast(usize)

Requires at least the specified length.

AtMost(usize)

Requires at most the specified length.

InRange

Requires a length between min and max, inclusive.

Fields

min: usize

The inclusive minimum length.

max: usize

The inclusive maximum length.
