Struct Characters 

pub struct Characters<'a> { /* private fields */ }

A DNS message characters. It is a sequence of characters, where the first byte is the length of the sequence.

Implementations

impl<'a> Characters<'a>

pub const fn new(bytes: &'a [u8]) -> Result<Self, DnsMessageError>

Create a new Characters from a byte slice. The first byte of the slice must be the length of the sequence. The maximum length of the sequence is checked and 255, the first byte, must be equal to the length of the slice minus 1, which is also checked. Use this function if you want to create a Characters from a byte slice of unknown length. If you know the length of the slice at compile time, use the dns_characters! macro instead.

pub const unsafe fn new_unchecked(bytes: &'a [u8]) -> Self

Create a new Characters from a byte slice. The first byte of the slice must be the length of the sequence. The maximum length of the sequence is not checked and 255, the first byte, must be equal to the length of the slice minus 1, which is also not checked, hence the unsafe. Using this function is unsafe cause it can lead to an invalid DNS message.

Trait Implementations

impl<'a> AsRef<[u8]> for Characters<'a>

fn as_ref(&self) -> &[u8]

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

impl<'a> Clone for Characters<'a>

fn clone(&self) -> Characters<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Characters<'a>

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

Formats the value using the given formatter.

impl<'a> Display for Characters<'a>

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

Formats the value using the given formatter.

impl<'a> PartialEq for Characters<'a>

fn eq(&self, other: &Characters<'a>) -> 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.
