Struct litrs::ByteStringLit

pub struct ByteStringLit<B: Buffer> { /* private fields */ }

A byte string or raw byte string literal, e.g. b"hello" or br#"abc"def"#.

See the reference for more information.

Implementations

impl<B: Buffer> ByteStringLit<B>

pub fn parse(input: B) -> Result<Self, ParseError>

Parses the input as a (raw) byte string literal. Returns an error if the input is invalid or represents a different kind of literal.

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

Returns the string value this literal represents (where all escapes have been turned into their respective values).

pub fn into_value(self) -> B::ByteCow

Like value but returns a potentially owned version of the value.

The return value is either Cow<'static, [u8]> if B = String, or Cow<'a, [u8]> if B = &'a str.

pub fn suffix(&self) -> &str

The optional suffix. Returns "" if the suffix is empty/does not exist.

pub fn is_raw_byte_string(&self) -> bool

Returns whether this literal is a raw string literal (starting with r).

pub fn raw_input(&self) -> &str

Returns the raw input that was passed to parse.

pub fn into_raw_input(self) -> B

Returns the raw input that was passed to parse, potentially owned.

impl ByteStringLit<&str>

pub fn into_owned(self) -> ByteStringLit<String>

Makes a copy of the underlying buffer and returns the owned version of Self.

Trait Implementations

impl<B: Clone + Buffer> Clone for ByteStringLit<B>

fn clone(&self) -> ByteStringLit<B>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<B: Debug + Buffer> Debug for ByteStringLit<B>

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

Formats the value using the given formatter.

impl<B: Buffer> Display for ByteStringLit<B>

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

Formats the value using the given formatter.

impl<B: Buffer> From<ByteStringLit<B>> for Literal

fn from(l: ByteStringLit<B>) -> Self

Converts to this type from the input type.

impl<B: Buffer> From<ByteStringLit<B>> for Literal<B>

fn from(src: ByteStringLit<B>) -> Self

Converts to this type from the input type.

impl<B: PartialEq + Buffer> PartialEq for ByteStringLit<B>

fn eq(&self, other: &ByteStringLit<B>) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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

impl TryFrom<&Literal> for ByteStringLit<String>

type Error = InvalidToken

The type returned in the event of a conversion error.

fn try_from(src: &Literal) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<&TokenTree> for ByteStringLit<String>

type Error = InvalidToken

The type returned in the event of a conversion error.

fn try_from(tt: &TokenTree) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<Literal> for ByteStringLit<String>

type Error = InvalidToken

The type returned in the event of a conversion error.

fn try_from(src: Literal) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<TokenTree> for ByteStringLit<String>

type Error = InvalidToken

The type returned in the event of a conversion error.

fn try_from(tt: TokenTree) -> Result<Self, Self::Error>

Performs the conversion.
