Function try_encode_empty_debug_log_into 

pub fn try_encode_empty_debug_log_into(
    record_capacity: u32,
    dst: &mut Vec<u8>,
) -> Result<(), ProtocolError>

Strictly encode an empty PRINTF channel buffer into caller-owned storage.

Clears and resizes dst to the exact debug-log byte length, reusing allocation.

Errors

Returns ProtocolError when the requested debug-log size overflows host address space.
