Trait ToDuckDbType

pub trait ToDuckDbType {
    type DuckDbRepresentation;

    const DUCKDB_TYPE_ID: TypeId;

    // Provided method
    fn logical_type() -> LogicalTypeHandle { ... }
}

Rust primitive types to duckdb types

Required Associated Constants

const DUCKDB_TYPE_ID: TypeId

Required Associated Types

type DuckDbRepresentation

Representation to interface with DuckDb

Provided Methods

fn logical_type() -> LogicalTypeHandle

Create a duckdb logical type structure for this type

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.
