Function dora_log 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn dora_log(
    context: *mut c_void,
    level_ptr: *const u8,
    level_len: usize,
    msg_ptr: *const u8,
    msg_len: usize,
) -> c_int

Sends a structured log message from a C node.

The level_ptr/level_len fields must point to a UTF-8 string containing one of: “error”, “warn”, “info”, “debug”, “trace”.

The msg_ptr/msg_len fields must point to a UTF-8 string with the log message.

Returns 0 on success, -1 on error.

Safety

• The context argument must be a valid dora context from init_dora_context_from_env.
• The pointer/length pairs must describe valid UTF-8 byte slices.
