Struct SpanContainer 

pub struct SpanContainer<'src, T> {
    pub span: Span<'src>,
    pub item: T,
}

A generic container to bundle a Span<'src> to an instance of type T it is representing. Written as SpanContainer<'src, T>

Fields

span: Span<'src>

A Span meant to represent the associated item stored alongside it.

item: T

A generic type item meant to be represented by the Span stored alongside it.

Implementations

impl<'src, T> SpanContainer<'src, T>

pub fn new(span: Span<'src>, item: T) -> Self

Constructs a SpanContainer with a provided span and item

pub fn boxed(self) -> SpanContainer<'src, Box<T>>

Consumes the current SpanContainer and returns another with an item wrapped in a Box.

pub fn map<M>(self, mapfn: fn(T) -> M) -> SpanContainer<'src, M>

Consumes the current SpanContainer and returns another with an item of type M returned by the mapfn closure.

Trait Implementations

impl<T> Clone for SpanContainer<'_, T>

where T: Clone,

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T> Debug for SpanContainer<'_, T>

where T: Debug,

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

Formats the value using the given formatter.

impl<T> Display for SpanContainer<'_, T>

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

Formats the value using the given formatter.

impl<T> PartialEq for SpanContainer<'_, 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> Eq for SpanContainer<'_, T>

where T: Eq,

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
