Trait FieldEncoder 

pub trait FieldEncoder<E, T: ?Sized>: ValueEncoder<E, T> {
    // Required methods
    fn encode_field<B: BufMut + ?Sized>(
        tag: u32,
        value: &T,
        buf: &mut B,
        tw: &mut TagWriter,

    );
    fn field_encoded_len(
        tag: u32,
        value: &T,
        tm: &mut impl TagMeasurer,
    ) -> usize;
}

Affiliated helper trait for ValueEncoder that provides obligate implementations for handling field keys and wire types.

Required Methods

fn encode_field<B: BufMut + ?Sized>( tag: u32, value: &T, buf: &mut B, tw: &mut TagWriter, )

Encodes exactly one field with the given tag and value into the buffer.

fn prepend_field<B: ReverseBuf + ?Sized>( tag: u32, value: &T, buf: &mut B, tw: &mut TagRevWriter, )

Prepends exactly one field with the given tag and value into the buffer.

fn field_encoded_len(tag: u32, value: &T, tm: &mut impl TagMeasurer) -> usize

Returns the encoded length of the field including its key.

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.
