Trait TypeInfo 

pub trait TypeInfo {
    const SQL_TYPE: SqlType;
    const NULLABLE: bool = false;
}

Trait for types that have a corresponding SQL type.

Required Associated Constants

const SQL_TYPE: SqlType

The SQL type for this Rust type.

Provided Associated Constants

const NULLABLE: bool = false

Whether this type is nullable by default.

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.
