Struct Sliced

pub struct Sliced<'source, T> { /* private fields */ }

A value of type T associated with a slice of the source text.

Implementations

impl<'source, T> Sliced<'source, T>

pub fn new(inner: T, span: Span, source: &'source str) -> Self

Creates a new Sliced value.

Parameters

• inner: The value to be wrapped.
• span: The range in the source text that corresponds to the value.
• source: The source text that the wrapped value corresponds to a slice of.

pub fn span(&self) -> Span

The span associated with the wrapped value.

pub fn slice(&self) -> &'source str

The slice associated with the wrapped value.

pub fn source(&self) -> &'source str

The source string associated with the wrapped value.

impl<'source, T, E> Sliced<'source, Result<T, E>>

pub fn unzip(self) -> Result<Sliced<'source, T>, Sliced<'source, E>>

Unzips an Sliced<Result<T, E>> into a Result<Sliced<T>, Sliced<E>>.

If inner is of the Ok variant this method returns Ok(Sliced { inner: t, .. }. Otherwise, Err(Sliced { inner: e, .. } is returned. Where t and e represent the Ok and Err values of the inner Result.

impl<'source, T> Sliced<'source, Option<T>>

pub fn unzip(self) -> Option<Sliced<'source, T>>

Unzips a Sliced<Option<T>> into a Option<Sliced<T>>.

If self is Sliced { inner: Some(a), .. } this method returns Some(Sliced { inner: a, ..}). Otherwise, None is returned.

impl<'source, T> Sliced<'source, &T>

pub fn copied(self) -> Sliced<'source, T>

where T: Copy,

Maps a Sliced<&T> to a Sliced<T> by copying the contents of the spanned.

pub fn cloned(self) -> Sliced<'source, T>

where T: Clone,

Maps a Sliced<&T> to a Sliced<T> by cloning the contents of the spanned.

impl<'source, T> Sliced<'source, &mut T>

pub fn copied(self) -> Sliced<'source, T>

where T: Copy,

Maps a Sliced<&mut T> to a Sliced<T> by copying the contents of the spanned.

pub fn cloned(self) -> Sliced<'source, T>

where T: Clone,

Maps a Sliced<&mut T> to a Sliced<T> by cloning the contents of the spanned.

Trait Implementations

impl<'source, T> AsMut<T> for Sliced<'source, T>

where <Sliced<'source, T> as Deref>::Target: AsMut<T>,

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

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

impl<'source, T> AsRef<T> for Sliced<'source, T>

where <Sliced<'source, T> as Deref>::Target: AsRef<T>,

fn as_ref(&self) -> &T

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

impl<'source, T> Clone for Sliced<'source, T>

where T: Clone,

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'source, T: Debug> Debug for Sliced<'source, T>

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

Formats the value using the given formatter.

impl<'source, T> Deref for Sliced<'source, T>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<'source, T> DerefMut for Sliced<'source, T>

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl<'a, 'source, T> From<&'a Sliced<'source, T>> for Sliced<'source, &'a T>

fn from(value: &'a Sliced<'source, T>) -> Self

Converts to this type from the input type.

impl<'a, 'source, T> From<&'a mut Sliced<'source, T>> for Sliced<'source, &'a mut T>

fn from(value: &'a mut Sliced<'source, T>) -> Self

Converts to this type from the input type.

impl<'source, T: PartialEq> PartialEq for Sliced<'source, T>

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.
