The different types of errors that can arise from this crate

Variants

ShuffleOutOfRange

This error is invoked when the caller attempts to use an index on the shuffle method that is larger than the size of the set.

The user can only shuffle indices that are within the set, otherwise the hashing algorithm does not work. shuffle is the index that the user called, and max_shuffle is the size of the permutation set (which is also the upper bound for the calling index).

impl Display for PermutationError

pub fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for PermutationError

pub fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

pub fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

pub fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

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

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
