CodecMemberShape

Enum CodecMemberShape 

Source
pub enum CodecMemberShape {
    Count,
    Bytes,
    Text,
    ClosedChoice,
    Nested,
}
Expand description

The wire shape one member is written under.

Five rows, every one a shape the rendering can write end to end: there is no opaque arm, because a member the rendering could not write would be a member whose bytes nobody could re-read.

Variants§

§

Count

A count, carried at the framing width and narrowed back at the member’s own type on the way in.

§

Bytes

Variable-length bytes, written length-prefixed.

§

Text

Variable-length text, written length-prefixed as its UTF-8 bytes and read back through a check that refuses.

§

ClosedChoice

One arm of a closed roster, written as that arm’s own declared position and read back by walking the roster the owner declared.

§

Nested

A nested value carrying its own codec, framed at its own length so the member after it stays readable.
