Trait PbWrite 

pub trait PbWrite {
    type Error;

    // Required method
    fn pb_write(&mut self, data: &[u8]) -> Result<(), Self::Error>;
}

A writer to which Protobuf data is written, similar to std::io::Write.

PbEncoder uses this trait as the interface for writing encoded Protobuf messages.

This trait is implemented for common byte vector types such as heapless::Vec and Vec. The implementations are feature-gated.

Required Associated Types

type Error

I/O error returned on write failure.

Required Methods

fn pb_write(&mut self, data: &[u8]) -> Result<(), Self::Error>

Writes all bytes in data.

This is analogous to std::io::Write::write_all.

Implementations on Foreign Types
