Trait Writer 

pub trait Writer: Sealed {
    // Required method
    fn write_bytes(&mut self, data: &[u8]) -> Result<(), DiagError>;
}

Abstraction over alloc and no-alloc write targets.

Implemented for:

• &mut [u8] - no-alloc, fixed-size buffer, advances cursor on write
• bytes::BytesMut - alloc, growable buffer (feature = “alloc”)

Sealed to prevent downstream implementations.

Required Methods

fn write_bytes(&mut self, data: &[u8]) -> Result<(), DiagError>
