Trait Operand 

pub trait Operand<M, T> {
    // Required method
    fn into_expr(self) -> Expr;
}

A value that can stand for a T column in a comparison or assignment: a T, a T for an Option<T> column, a primary key or model reference for a foreign key, or another typed handle of type T.

Required Methods

fn into_expr(self) -> Expr

Convert into an expression.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
