Trait PrimitiveEncode

trait PrimitiveEncode: ArrowNativeType {
    type Buffer;

    // Required methods
    fn init_buffer() -> Self::Buffer;
    fn encode(self, buf: &mut Self::Buffer) -> &[u8] ;
}

Required Associated Types

type Buffer

Required Methods

fn init_buffer() -> Self::Buffer

fn encode(self, buf: &mut Self::Buffer) -> &[u8]

Encode the primitive value as bytes, returning a reference to that slice.

buf is temporary space that may be used

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.
