Trait SqlTyped 

pub trait SqlTyped {
    const SQL_TYPE: &'static str;
}

Associates a Rust type with its SQL type name so a typed NULL can be declared without a value (see null).

SQL_TYPE must match what ToSql::sql_type returns for a value of the same type.

Required Associated Constants

const SQL_TYPE: &'static str

The SQL type name for this Rust type.

Dyn Compatibility

This trait is not dyn compatible.

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