Trait SQLParam 

pub trait SQLParam: Clone + Debug {
    type DialectMarker: DialectTypes;

    const DIALECT: Dialect;
}

A marker trait for types that can be used as SQL parameters.

This trait is used as a bound on the parameter type in SQL fragments. It ensures type safety when building SQL queries with parameters.

Required Associated Constants

const DIALECT: Dialect

The SQL dialect for this parameter type

Required Associated Types

type DialectMarker: DialectTypes

Type-level dialect marker for compile-time dispatch.

Used by crate::row::SQLTypeToRust to select dialect-specific type mappings and by crate::dialect::DialectTypes to resolve conceptual SQL types to dialect-native markers.

Dyn Compatibility

This trait is not dyn compatible.

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