Crate vld_diesel 

vld-diesel — Diesel integration for the vld validation library

Validate data before inserting into the database, and use strongly-typed validated column types.

Quick Start

use vld_diesel::prelude::*;

// 1. Define a vld schema for your insertable struct
vld::schema! {
    #[derive(Debug)]
    pub struct NewUserSchema {
        pub name: String  => vld::string().min(1).max(100),
        pub email: String => vld::string().email(),
    }
}

// 2. Wrap your Diesel Insertable with Validated
let new_user = NewUser { name: "Alice".into(), email: "alice@example.com".into() };
let validated = Validated::<NewUserSchema, _>::new(new_user)?;

// 3. Insert — the inner value is guaranteed to be valid
diesel::insert_into(users::table)
    .values(validated.inner())
    .execute(&mut conn)?;

Validated column types

Use VldText for columns that must always satisfy a validation schema:

use vld_diesel::VldText;

let email = VldText::<EmailSchema>::new("user@example.com")?;

Re-exports

pub use vld;

Modules
