pub struct Label(_);

Expand description

Labels are always stored as ASCII, unicode characters must be encoded with punycode

Implementations

source

impl Label

source

pub fn from_raw_bytes(bytes: &[u8 ]) -> ProtoResult<Self>

These must only be ASCII, with unicode encoded to PunyCode, or other such transformation.

This uses the bytes as raw ascii values, with nothing escaped on the wire. Generally users should use from_str or from_ascii

source

pub fn from_utf8(s: &str) -> ProtoResult<Self>

Translates this string into IDNA safe name, encoding to punycode as necessary.

source

pub fn from_ascii(s: &str) -> ProtoResult<Self>

Takes the ascii string and returns a new label.

This will return an Error if the label is not an ascii string

source

pub fn wildcard() -> Self

Returns a new Label of the Wildcard, i.e. “*”

source

pub fn to_lowercase(&self) -> Self

Converts this label to lowercase

source

pub fn is_wildcard(&self) -> bool

Returns true if this label is the wildcard, ‘*’, label

source

pub fn len(&self) -> usize

Returns the lenght in bytes of this label

source

pub fn is_empty(&self) -> bool

True if the label contains no characters

source

pub fn as_bytes(&self) -> &[u8 ]ⓘNotable traits for &'_ mut [u8 ]`impl<'_> Write for &'_ mut [u8]impl<'_> Read for &'_ [u8]`

Returns the raw bytes of the label, this is good for writing to the wire.

See Display for presentation version (unescaped from punycode, etc)

source

pub fn eq_ignore_ascii_case(&self, other: &Self) -> bool

Performs the equivalence operation disregarding case

source

pub fn cmp_with_f<F: LabelCmp>(&self, other: &Self) -> Ordering

compares with the other label, ignoring case

source

pub fn to_utf8(&self) -> String

Performs the conversion to utf8 from IDNA as necessary, see fmt for more details

source

pub fn to_ascii(&self) -> String

Converts this label to safe ascii, escaping characters as necessary

If this is an IDNA, punycode, label, then the xn– prefix will be maintained as ascii

source

pub fn write_ascii<W: Write>(&self, f: &mut W) -> Result<(), Error>

Writes this label to safe ascii, escaping characters as necessary

Trait Implementations

source

impl AsRef<[u8 ]> for Label

source

source

source

impl Display for Label

source

outputs characters in a safe string manner.

if the string is punycode, i.e. starts with xn--, otherwise it translates to a safe ascii string escaping characters as necessary.
