Enum LengthConstraint 

#[non_exhaustive]
pub enum LengthConstraint {
    Exact(usize),
    AtLeast(usize),
    AtMost(usize),
    Between {
        min: usize,
        max: usize,
    },
}

A constraint on a byte or buffer length.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Exact(usize)

The length must equal this value.

AtLeast(usize)

The length must be at least this value.

AtMost(usize)

The length must be at most this value.

Between

The length must be within this inclusive range.

Fields

min: usize

max: usize
