Struct VldInt 

pub struct VldInt<S> { /* private fields */ }

A validated integer column type.

Wraps an i64 and ensures it passes the vld schema S on construction. Implements SQLx Type, Encode, Decode for any database where i64 does.

The schema must have a field named value.

Example

use vld::prelude::*;

vld::schema! {
    #[derive(Debug)]
    pub struct AgeField {
        pub value: i64 => vld::number().int().min(0).max(150),
    }
}

let age = vld_sqlx::VldInt::<AgeField>::new(25).unwrap();
assert_eq!(*age, 25);
assert!(vld_sqlx::VldInt::<AgeField>::new(-1).is_err());
