Enum StringLiteralPrefix 

pub enum StringLiteralPrefix {
    Empty,
    Unicode,
    Raw {
        uppercase: bool,
    },
}

Enumerations of the valid prefixes a string literal can have.

Bytestrings and f-strings are excluded from this enumeration, as they are represented by different AST nodes.

Variants

Empty

Just a regular string with no prefixes

Unicode

A string with a u or U prefix, e.g. u"foo". Note that, despite this variant’s name, it is in fact a no-op at runtime to use the u or U prefix in Python. All Python-3 strings are unicode strings; this prefix is only allowed in Python 3 for backwards compatibility with Python 2. However, using this prefix in a Python string is mutually exclusive with an r or R prefix.

Raw

A “raw” string, that has an r or R prefix, e.g. r"foo\." or R'bar\d'.

Fields

uppercase: bool

Implementations

impl StringLiteralPrefix

pub const fn is_empty(&self) -> bool

Returns true if self is of variant Empty.

pub const fn is_unicode(&self) -> bool

Returns true if self is of variant Unicode.

pub const fn is_raw(&self) -> bool

Returns true if self is of variant Raw.

impl StringLiteralPrefix

pub const fn as_str(self) -> &'static str

Return a str representation of the prefix

pub const fn text_len(self) -> TextSize

Trait Implementations

impl Clone for StringLiteralPrefix

fn clone(&self) -> StringLiteralPrefix

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StringLiteralPrefix

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

Formats the value using the given formatter.

impl Display for StringLiteralPrefix

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

Formats the value using the given formatter.

impl Hash for StringLiteralPrefix

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 PartialEq for StringLiteralPrefix

fn eq(&self, other: &StringLiteralPrefix) -> 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.
