ssh_format

Data format used to communicate with openssh mux server.

Format details:

• All integers are encoded in big endian;
• Boolean are encoded as u32 according to here;
• char are encoded as u32;
• Strings and bytes are encoded as length(u32) + content, same as sshbuf_put_string;
• Option::None are omitted while Option::Some(v) has the same encoding as v since openssh mux protocol allows optional parameter at the end of the message;
• struct/tuple are encoded as-is, unit struct/tuple are omitted;
• sequence are encoded as if it is a tuple according to here, thus it cannot be deserialized;
• Variant is encoded as index(u32) + content encoded as-is (it is expected to manually implement Serialize and Deserialize to ensure the variant_index is the one you expected);
• Serializing/Deserializing map is unsupported;

Feature

• is_human_readable enables Serializer::is_human_readable and Deserializer::is_human_readable.
