Trait NumericTarget 

pub trait NumericTarget:
    Sized
    + Copy
    + 'static {
    const TARGET: DT;

    // Required method
    fn widen_from(src: DT, bytes: &[u8]) -> Result<Vec<Self>, String>;
}

Sealed trait implemented for each numeric primitive that the WXF derive / hand-impl path can read into. Each impl knows its target DT and how to widen from any compatible source DT.

Required Associated Constants

const TARGET: DT

The wire type this target maps to on the canonical (no-widening) path.

Required Methods

fn widen_from(src: DT, bytes: &[u8]) -> Result<Vec<Self>, String>

Build a Vec<Self> from a source data-type tag plus raw little-endian bytes. Returns Err(message) when the source can’t widen losslessly into Self (truncation, signedness change, precision loss).

Dyn Compatibility

This trait is not dyn compatible.

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