Struct RawTag 

pub struct RawTag<'a>(pub &'a [u8]);

A tag value.

Provides helper methods for decoding backslash escaped values.

A quote inside a string is represented by the backslash immediately followed by a quote. A backslash inside a string is represented by two adjacent backslashes.

Tuple Fields

0: &'a [u8]

Implementations

impl<'a> RawTag<'a>

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

Returns the raw byte representation of the tag value.

pub fn decode(&self) -> Cow<'a, [u8]>

Decodes escaped quotes and backslashes into bytes. Allocates only when the value actually contains escape sequences.

pub fn decode_utf8(&self) -> Result<Cow<'a, str>, Utf8Error>

Tries to decode the tag as UTF-8. This is guaranteed to succeed on valid PGNs.

Errors

Errors if the tag contains an invalid UTF-8 byte sequence.

pub fn decode_utf8_lossy(&self) -> Cow<'a, str>

Decodes the tag as UTF-8, replacing any invalid byte sequences with the placeholder � U+FFFD.

Trait Implementations

impl<'a> Clone for RawTag<'a>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for RawTag<'a>

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

Formats the value using the given formatter.

impl<'a> Hash for RawTag<'a>

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

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'a> PartialEq for RawTag<'a>

fn eq(&self, other: &RawTag<'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.
