Struct Spanned

pub struct Spanned<T> { /* private fields */ }

A wrapper type for attaching span information to a value.

Implementations

impl<T> Spanned<T>

pub fn new(value: T) -> Spanned<T>

Creates a new Spanned<T> from a T.

pub fn into_value(self) -> T

Consumes the Spanned<T> and returns the wrapped value.

pub fn value(&self) -> &T

Returns a reference to the wrapped value.

pub fn value_mut(&mut self) -> &mut T

Returns a mutable reference to the wrapped value.

pub fn value_into<U>(self) -> U

where T: Into<U>,

Consumes the Spanned<T> and converts the inner value into another type.

Trait Implementations

impl<T> AsMut<T> for Spanned<T>

fn as_mut(&mut self) -> &mut T

Converts this type into a mutable reference of the (usually inferred) input type.

impl<T> AsRef<T> for Spanned<T>

fn as_ref(&self) -> &T

Converts this type into a shared reference of the (usually inferred) input type.

impl<T: Clone> Clone for Spanned<T>

fn clone(&self) -> Spanned<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for Spanned<T>

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

Formats the value using the given formatter.

impl<T> Deref for Spanned<T>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &T

Dereferences the value.

impl<T> DerefMut for Spanned<T>

fn deref_mut(&mut self) -> &mut T

Mutably dereferences the value.

impl<T> Display for Spanned<T>

where T: Encode,

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

Formats the value using the given formatter.

impl From<Spanned<String>> for Element

fn from(value: Spanned<String>) -> Self

Converts to this type from the input type.

impl<T> From<T> for Spanned<T>

fn from(value: T) -> Self

Converts to this type from the input type.

impl<T> PartialEq for Spanned<T>

where T: PartialEq,

fn eq(&self, other: &Self) -> 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<T> Span for Spanned<T>

fn span(&self) -> Option<Range<usize>>

Obtains the span information. This only returns Some if the value was emitted by the parser.
