Function parse_stream_request_ext 

pub fn parse_stream_request_ext(
    remainder: &[u8],
) -> Result<StreamRequestExt, Error>

Parse the trailing StreamRequestExt bytes returned as the remainder by crate::decode_message after a ClientMessage::StreamRequest.

An empty remainder ⇒ StreamRequestExt::default (no client binding, no capability). Trailing bytes beyond the known fields are tolerated for forward compatibility (ADR 013 §Tier 1): a future optional field appended to StreamRequestExt is read by new receivers and skipped by old ones.

Errors

Returns a postcard::Error if a non-empty remainder is not a valid StreamRequestExt prefix.
