Struct ExprFString 

pub struct ExprFString {
    pub node_index: AtomicNodeIndex,
    pub range: TextRange,
    pub value: FStringValue,
}

An AST node that represents either a single-part f-string literal or an implicitly concatenated f-string literal.

This type differs from the original Python AST JoinedStr in that it doesn’t join the implicitly concatenated parts into a single string. Instead, it keeps them separate and provide various methods to access the parts.

Fields

node_index: AtomicNodeIndex

range: TextRange

value: FStringValue

Implementations

impl ExprFString

pub const fn as_single_part_fstring(&self) -> Option<&FString>

Returns the single FString if the f-string isn’t implicitly concatenated, None otherwise.

Trait Implementations

impl Clone for ExprFString

fn clone(&self) -> ExprFString

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExprFString

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

Formats the value using the given formatter.

impl<'a> From<&'a ExprFString> for AnyNodeRef<'a>

fn from(node: &'a ExprFString) -> AnyNodeRef<'a>

Converts to this type from the input type.

impl<'a> From<&'a ExprFString> for ExprRef<'a>

fn from(node: &'a ExprFString) -> ExprRef<'a>

Converts to this type from the input type.

impl<'a> From<&'a ExprFString> for StringLike<'a>

fn from(value: &'a ExprFString) -> StringLike<'a>

Converts to this type from the input type.

impl From<ExprFString> for Expr

fn from(node: ExprFString) -> Expr

Converts to this type from the input type.

impl GetSize for ExprFString

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 HasNodeIndex for ExprFString

fn node_index(&self) -> &AtomicNodeIndex

Returns the AtomicNodeIndex for this node.

impl PartialEq for ExprFString

fn eq(&self, other: &ExprFString) -> 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 Ranged for ExprFString

fn range(&self) -> TextRange

The range of this item in the source text.

fn start(&self) -> TextSize

The start offset of this item in the source text.

fn end(&self) -> TextSize

The end offset of this item in the source text.

impl<'a> TryFrom<AnyRootNodeRef<'a>> for &'a ExprFString

type Error = ()

The type returned in the event of a conversion error.

fn try_from(node: AnyRootNodeRef<'a>) -> Result<&'a ExprFString, ()>

Performs the conversion.
