Trait IntoLiteral 

pub trait IntoLiteral {
    // Required method
    fn into_literal(self) -> Expr;
}

Conversion trait for types that can be turned into a SQL literal Expr.

This trait is used by lit() to accept various Rust primitive types and convert them into the appropriate SQL literal representation.

Implemented for:

• &str, String – produce a SQL string literal (e.g. 'hello').
• i32, i64, usize, f64 – produce a SQL numeric literal (e.g. 42, 3.14).
• bool – produce a SQL boolean literal (TRUE or FALSE).

Required Methods

fn into_literal(self) -> Expr

Convert this value into a literal Expr.
