Struct Spanned

pub struct Spanned<T> {
    pub v: T,
    pub span: Span,
}

A value with a span locating it in the source code.

Fields

v: T

The spanned value.

span: Span

The value’s location in source code.

Implementations

impl<T> Spanned<T>

pub fn new(v: T, span: Span) -> Self

Create a new instance from a value and its span.

pub fn as_ref(&self) -> Spanned<&T>

Convert from &Spanned<T> to Spanned<&T>

pub fn map<F, U>(self, f: F) -> Spanned<U>

where F: FnOnce(T) -> U,

Map the value using a function.

Trait Implementations

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: Hash> Hash for Spanned<T>

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<T: PartialEq> PartialEq for Spanned<T>

fn eq(&self, other: &Spanned<T>) -> 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.
