Expand description

A trait for database types that can be divided by each other.

Required Methods§

Source

fn div<V: Into<T>>(self, other: V) -> Expr

Creates an expression that divides the field by the given value.

§Examples
use cot::db::query::{Expr, ExprDiv, Query};
use cot::db::{model, query};

#[model]
struct MyModel {
    #[model(primary_key)]
    id: i32,
};

let expr = <MyModel as cot::db::Model>::Fields::id.div(2);

assert_eq!(
    <Query<MyModel>>::new().filter(Expr::eq(Expr::field("id"), expr)),
    query!(MyModel, $id == $id / 2)
);

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
