Struct CharStrBuf 

pub struct CharStrBuf { /* private fields */ }

Available on crate feature unstable-new only.

A 256-byte buffer for a character string.

Implementations

impl CharStrBuf

pub fn copy_from(string: &CharStr) -> Self

Copy a CharStrBuf into a buffer.

impl CharStrBuf

pub fn wire_bytes(&self) -> &[u8]

The wire format for this character string.

Methods from Deref<Target = CharStr>

pub fn len(&self) -> usize

The length of the CharStr.

This is always less than 256 – it is guaranteed to fit in a u8.

pub fn is_empty(&self) -> bool

Whether the CharStr is empty.

Trait Implementations

impl AsMut<CharStr> for CharStrBuf

fn as_mut(&mut self) -> &mut CharStr

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

impl AsRef<CharStr> for CharStrBuf

fn as_ref(&self) -> &CharStr

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

impl Borrow<CharStr> for CharStrBuf

fn borrow(&self) -> &CharStr

Immutably borrows from an owned value.

impl BorrowMut<CharStr> for CharStrBuf

fn borrow_mut(&mut self) -> &mut CharStr

Mutably borrows from an owned value.

impl BuildBytes for CharStrBuf

fn build_bytes<'b>( &self, bytes: &'b mut [u8], ) -> Result<&'b mut [u8], TruncationError>

Serialize into a byte sequence.

fn built_bytes_size(&self) -> usize

The size of self when serialized into a byte sequence.

impl BuildInMessage for CharStrBuf

fn build_in_message( &self, contents: &mut [u8], start: usize, name: &mut NameCompressor, ) -> Result<usize, TruncationError>

Write this object in a DNS message.

impl Clone for CharStrBuf

fn clone(&self) -> CharStrBuf

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CharStrBuf

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

Formats the value using the given formatter.

impl Deref for CharStrBuf

type Target = CharStr

The resulting type after dereferencing.

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

Dereferences the value.

impl DerefMut for CharStrBuf

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

Mutably dereferences the value.

impl Eq for CharStrBuf

impl FromStr for CharStrBuf

fn from_str(s: &str) -> Result<Self, Self::Err>

Parse a DNS “character-string” from a string.

This is intended for easily constructing hard-coded character strings. This function cannot parse all valid character strings; if exceptional instances are needed, use CharStr::from_bytes_unchecked().

type Err = CharStrParseError

The associated error which can be returned from parsing.

impl ParseBytes<'_> for CharStrBuf

fn parse_bytes(bytes: &[u8]) -> Result<Self, ParseError>

Parse a value of Self from the given byte sequence.

impl ParseMessageBytes<'_> for CharStrBuf

fn parse_message_bytes( contents: &[u8], start: usize, ) -> Result<Self, ParseError>

Parse a value from bytes in a DNS message.

impl PartialEq for CharStrBuf

fn eq(&self, that: &Self) -> bool

Equality operator ==.

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

Inequality operator !=.

impl SplitBytes<'_> for CharStrBuf

fn split_bytes(bytes: &[u8]) -> Result<(Self, &[u8]), ParseError>

Parse a value of Self from the start of the byte sequence.

impl SplitMessageBytes<'_> for CharStrBuf

fn split_message_bytes( contents: &[u8], start: usize, ) -> Result<(Self, usize), ParseError>

Parse a value from the start of a byte sequence within a DNS message.

impl UnsizedCopyFrom for CharStrBuf

type Source = CharStr

The source type to copy from.

fn unsized_copy_from(value: &Self::Source) -> Self

Create a new Self by copying the given value.
