pub struct CanvasError {
    pub width: u32,
    pub height: u32,
    pub scale: f32,
    pub bytes: usize,
}

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
