Trait Implementations

impl Clone for Code

fn clone(&self) -> Code

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Code

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

Formats the value using the given formatter.

impl Default for Code

fn default() -> Code

Returns the “default value” for a type.

impl Display for Code

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

Formats the value using the given formatter.

impl FromStr for Code

type Err = UnrecognizedCodeError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Code, <Code as FromStr>::Err>

Parses a string s to return a value of this type.

impl Hash for Code

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

where __H: Hasher,

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

impl PartialEq for Code

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

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

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