Struct Identity

pub struct Identity {}

Encoding which does not transform data and returns the original input.

Trait Implementations

impl Clone for Identity

fn clone(&self) -> Identity

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Identity

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

Formats the value using the given formatter.

impl Default for Identity

fn default() -> Identity

Returns the “default value” for a type.

impl Encoding for Identity

fn encode_to_slice(&self, src: &[u8], dst: &mut [u8]) -> Result<usize, Error>

Encode the given slice into the destination buffer.

fn encoded_len(&self, bytes: &[u8]) -> usize

Calculate the length of the given data after encoding.

fn decode_to_slice(&self, src: &[u8], dst: &mut [u8]) -> Result<usize, Error>

Decode hexadecimal (upper or lower case) with branchless / secret-independent logic

fn decoded_len(&self, bytes: &[u8]) -> Result<usize, Error>

Calculate the length of the given data after decoding.

fn encode<B: AsRef<[u8]>>(&self, bytes: B) -> Vec<u8>

Encode the given buffer, returning a Vec<u8>

fn encode_to_string<B: AsRef<[u8]>>(&self, bytes: B) -> Result<String, Error>

Encode the given slice to a String with this Encoding.

fn encode_to_writer<B, W>( &self, bytes: B, writer: &mut W, ) -> Result<usize, Error>

where B: AsRef<[u8]>, W: Write,

Encode the given slice with this Encoding, writing the result to the supplied io::Write type, returning the number of bytes written or a Error.

fn encode_to_file<B, P>(&self, bytes: B, path: P) -> Result<File, Error>

where B: AsRef<[u8]>, P: AsRef<Path>,

Encode self and write it to a file at the given path, returning the resulting File or a Error.

fn decode<B: AsRef<[u8]>>(&self, encoded_bytes: B) -> Result<Vec<u8>, Error>

Decode the given buffer, returning a Vec<u8>

fn decode_from_str<S: AsRef<str>>(&self, encoded: S) -> Result<Vec<u8>, Error>

Decode the given string-alike type with this Encoding, returning the decoded value or a Error.

fn decode_from_reader<R: Read>(&self, reader: &mut R) -> Result<Vec<u8>, Error>

Decode the data read from the given io::Read type with this Encoding, returning the decoded value or a Error.

fn decode_from_file<P: AsRef<Path>>(&self, path: P) -> Result<Vec<u8>, Error>

Read a file at the given path, decoding the data it contains using the provided Encoding, returning the decoded value or a Error.

impl Hash for Identity

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Identity

fn cmp(&self, other: &Identity) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Identity

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for Identity

fn partial_cmp(&self, other: &Identity) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
