Trait OutputDatumType 

pub trait OutputDatumType<'a, E>: Sized {
    // Required methods
    fn nullable() -> bool;
    fn fallible() -> bool;
    fn into_result(self, temp_storage: &'a RowArena) -> Result<Datum<'a>, E>;
}

A bridge between native Rust types and SQL runtime types represented in Datums

Required Methods

fn nullable() -> bool

Whether this Rust type can represent NULL values

fn fallible() -> bool

Whether this Rust type can represent errors

fn into_result(self, temp_storage: &'a RowArena) -> Result<Datum<'a>, E>

Convert this Rust type into a Result containing a Datum, or an error

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.
