Struct TStringValue 

pub struct TStringValue { /* private fields */ }

The value representing an ExprTString.

Implementations

impl TStringValue

pub fn single(value: TString) -> TStringValue

Creates a new t-string literal with a single TString part.

pub fn concatenated(values: Vec<TString>) -> TStringValue

Creates a new t-string with the given values that represents an implicitly concatenated t-string.

Panics

Panics if values has less than 2 elements. Use TStringValue::single instead.

pub fn is_implicit_concatenated(&self) -> bool

Returns true if the t-string is implicitly concatenated, false otherwise.

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

Returns a slice of all the TStrings contained in this value.

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

Returns an iterator over all the TStrings contained in this value.

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

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

pub fn elements(&self) -> impl Iterator<Item = &InterpolatedStringElement>

Returns an iterator over all the InterpolatedStringElement contained in this value.

An interpolated string element is what makes up an TString i.e., it is either a string literal or an interpolation. In the following example,

t"foo" t"bar {x}" t"baz" t"qux"

The interpolated string elements returned would be string literal ("bar "), interpolation (x) and string literal ("qux").

pub fn is_empty_iterable(&self) -> bool

Returns true if the node represents an empty t-string in the sense that __iter__ returns an empty iterable.

Beware that empty t-strings are still truthy, i.e. bool(t"") == True.

Note that a TStringValue node will always contain at least one TString node. This method checks whether each of the constituent t-strings (in an implicitly concatenated t-string) are empty in the above sense.

Trait Implementations

impl Clone for TStringValue

fn clone(&self) -> TStringValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TStringValue

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

Formats the value using the given formatter.

impl<'a> From<&'a TStringValue> for ComparableTString<'a>

fn from(value: &'a TStringValue) -> ComparableTString<'a>

Converts to this type from the input type.

impl GetSize for TStringValue

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 TStringValue

type Item = &'a TString

The type of the elements being iterated over.

type IntoIter = Iter<'a, TString>

Which kind of iterator are we turning this into?

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

Creates an iterator from a value.

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

type Item = &'a mut TString

The type of the elements being iterated over.

type IntoIter = IterMut<'a, TString>

Which kind of iterator are we turning this into?

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

Creates an iterator from a value.

impl PartialEq for TStringValue

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