Struct ExactWidthError 

pub struct ExactWidthError { /* private fields */ }

Error returned when an exact-width byte value has the wrong length.

pub const fn expected(&self) -> usize

Returns the required byte length.

pub const fn actual(&self) -> usize

Returns the supplied byte length.

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
