Struct type_rules::rules::MinLength

source · [−]

pub struct MinLength(pub usize);

Expand description

Rule to constraint the minimum length of a String or &str

Works with Option, just return Ok(()) if it’s None

Example

use type_rules::Validator;
use type_rules::rules::MinLength;

#[derive(Validator)]
struct Password(#[rule(MinLength(8))] String);
