Trait IntoExpr

pub trait IntoExpr<'column, S>: Clone {
    type Typ: MyTyp;

    // Required method
    fn into_expr(self) -> Expr<'column, S, Self::Typ>;
}

Trait for all values that can be used as expressions in queries.

Required Associated Types

type Typ: MyTyp

The type of the expression.

Required Methods

fn into_expr(self) -> Expr<'column, S, Self::Typ>

Turn this value into an Expr.

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.
