786-788: Add documentation for the mark_protocol_type function.The function performs bit manipulation to combine protocol type and source, but lacks documentation explaining its purpose and the bit manipulation logic.
Add documentation like this:
+/// Combines a source integer with a serialization type into a marked protocol type. +/// +/// # Arguments +/// * `source` - The source integer (uses lower 24 bits) +/// * `serialize_type` - The serialization type (uses upper 8 bits) +/// +/// # Returns +/// A 32-bit integer where the upper 8 bits contain the serialization type code +/// and the lower 24 bits contain the source value. pub fn mark_protocol_type(source: i32, serialize_type: SerializeType) -> i32 { ((serialize_type.get_code() as i32) << 24) | (source & 0x00FFFFFF) }

387-393: LGTM! Clean implementation of header encoding.The method correctly handles both cases where a body is present or absent.

Handle potential panic in header encoding.
The unwrap() call on line 400 could panic if header_encode() returns None. Consider using proper error handling.
Here's a suggested fix:
- let header_data = self.header_encode().unwrap();
+ let header_data = self.header_encode().ok_or_else(||
+ RemotingError::RemotingCommandError("Failed to encode header".to_string())
+ )?;Also update the function signature to:
- pub fn encode_header_with_body_length(&self, body_length: usize) -> Option<Bytes>
+ pub fn encode_header_with_body_length(&self, body_length: usize) -> crate::Result<Option<Bytes>>Committable suggestion skipped: line range outside the PR's diff.
