Struct Length 

pub struct Length {
    pub min: Option<usize>,
    pub max: Option<usize>,
    pub exact: Option<usize>,
    pub min_message: String,
    pub max_message: String,
    pub exact_message: String,
}

Validates that a string length is within a given range.

Equivalent to Symfony’s Length constraint.
