Enum bitstream_io::huffman::HuffmanTreeError

pub enum HuffmanTreeError {
    InvalidBit,
    MissingLeaf,
    DuplicateLeaf,
    OrphanedLeaf,
}

An error type during Huffman tree compilation.

Variants

InvalidBit

One of the bits in a Huffman code is not 0 or 1

MissingLeaf

A Huffman code in the specification has no defined symbol

DuplicateLeaf

The same Huffman code specifies multiple symbols

OrphanedLeaf

A Huffman code is the prefix of some longer code

Trait Implementations

impl Clone for HuffmanTreeError

fn clone(&self) -> HuffmanTreeError

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for HuffmanTreeError

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

Formats the value using the given formatter.

impl Display for HuffmanTreeError

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

Formats the value using the given formatter.

impl Error for HuffmanTreeError

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

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

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

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

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

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

impl PartialEq<HuffmanTreeError> for HuffmanTreeError

fn eq(&self, other: &HuffmanTreeError) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=.
