Struct StringLiteralValue 

pub struct StringLiteralValue { /* private fields */ }

The value representing a ExprStringLiteral.

Implementations

impl StringLiteralValue

pub fn single(string: StringLiteral) -> StringLiteralValue

Creates a new string literal with a single StringLiteral part.

pub fn first_literal_flags(&self) -> StringLiteralFlags

Returns the StringLiteralFlags associated with this string literal.

For an implicitly concatenated string, it returns the flags for the first literal.

pub fn concatenated(strings: Vec<StringLiteral>) -> StringLiteralValue

Creates a new string literal with the given values that represents an implicitly concatenated strings.

Panics

Panics if strings has less than 2 elements. Use StringLiteralValue::single instead.

pub const fn is_implicit_concatenated(&self) -> bool

Returns true if the string literal is implicitly concatenated.

pub fn is_unicode(&self) -> bool

Returns true if the string literal has a u prefix, e.g. u"foo".

Although all strings in Python 3 are valid unicode (and the u prefix is only retained for backwards compatibility), these strings are known as “unicode strings”.

For an implicitly concatenated string, it returns true only if the first StringLiteral has the u prefix.

pub fn as_slice(&self) -> &[StringLiteral]

Returns a slice of all the StringLiteral parts contained in this value.

pub fn iter(&self) -> Iter<'_, StringLiteral>

Returns an iterator over all the StringLiteral parts contained in this value.

pub fn iter_mut(&mut self) -> IterMut<'_, StringLiteral>

Returns an iterator over all the StringLiteral parts contained in this value that allows modification.

pub fn is_empty(&self) -> bool

Returns true if the node represents an empty string.

Note that a StringLiteralValue node will always have >=1 StringLiteral parts inside it. This method checks whether the value of the concatenated parts is equal to the empty string, not whether the string has 0 parts inside it.

pub fn len(&self) -> usize

Returns the total length of the string literal value, in bytes, not chars or graphemes.

pub fn chars(&self) -> impl Iterator<Item = char> + Clone

Returns an iterator over the chars of each string literal part.

pub fn to_str(&self) -> &str

Returns the concatenated string value as a str.

Note that this will perform an allocation on the first invocation if the string value is implicitly concatenated.

Trait Implementations

impl Clone for StringLiteralValue

fn clone(&self) -> StringLiteralValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StringLiteralValue

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

Formats the value using the given formatter.

impl Display for StringLiteralValue

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

Formats the value using the given formatter.

impl GetSize for StringLiteralValue

fn get_heap_size(&self) -> usize

Determines how many bytes this object occupies inside the heap.

fn get_heap_size_with_tracker<TRACKER>( &self, tracker: TRACKER, ) -> (usize, TRACKER)

where TRACKER: GetSizeTracker,

Determines how many bytes this object occupies inside the heap while using a tracker.

fn get_stack_size() -> usize

Determines how may bytes this object occupies inside the stack.

fn get_size(&self) -> usize

Determines the total size of the object.

fn get_size_with_tracker<T>(&self, tracker: T) -> (usize, T)

where T: GetSizeTracker,

Determines the total size of the object while using a tracker.

impl<'a> IntoIterator for &'a StringLiteralValue

type Item = &'a StringLiteral

The type of the elements being iterated over.

type IntoIter = Iter<'a, StringLiteral>

Which kind of iterator are we turning this into?

fn into_iter(self) -> <&'a StringLiteralValue as IntoIterator>::IntoIter

Creates an iterator from a value.

impl<'a> IntoIterator for &'a mut StringLiteralValue

type Item = &'a mut StringLiteral

The type of the elements being iterated over.

type IntoIter = IterMut<'a, StringLiteral>

Which kind of iterator are we turning this into?

fn into_iter(self) -> <&'a mut StringLiteralValue as IntoIterator>::IntoIter

Creates an iterator from a value.

impl PartialEq<str> for StringLiteralValue

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

impl PartialEq for StringLiteralValue

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