Trait Implementations

impl Add for ByteString

type Output = ByteString

The resulting type after applying the + operator.

fn add(self, rhs: Self) -> Self::Output

Performs the + operation.

impl AsRef<str> for ByteString

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for ByteString

fn clone(&self) -> ByteString

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ByteString

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

Formats the value using the given formatter.

impl Deref for ByteString

type Target = Val

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl DerefMut for ByteString

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl Display for ByteString

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

impl PartialEq<str> for ByteString

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

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

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