Struct ConstraintLength 

pub struct ConstraintLength {
    pub min: Option<u64>,
    pub max: Option<u64>,
}

A length constraint for string fields.

Enforces minimum and/or maximum character-count bounds on a string value. Either bound can be None to leave that side unconstrained.

Examples

use toasty_core::schema::app::ConstraintLength;

let c = ConstraintLength { min: Some(1), max: Some(255) };
assert_eq!(c.min, Some(1));
assert_eq!(c.max, Some(255));

Fields

min: Option<u64>

The minimum length of the field. None means no lower bound.

max: Option<u64>

The maximum length of the field. None means no upper bound.
