Trait Implementations

impl Clone for Span

fn clone(&self) -> Span

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Span

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

Formats the value using the given formatter.

impl Default for Span

fn default() -> Span

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Span

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<Range<usize>> for Span

fn from(value: Range<usize>) -> Self

Converts to this type from the input type.

impl From<Span> for Range<usize>

fn from(value: Span) -> Self

Converts to this type from the input type.

impl FromIterator<Span> for Mask

fn from_iter<T: IntoIterator<Item = Span>>(iter: T) -> Self

Creates a value from an iterator.

impl IntoIterator for Span

type Item = usize

The type of the elements being iterated over.

type IntoIter = Range<usize>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl PartialEq for Span

fn eq(&self, other: &Span) -> 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 Serialize for Span

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Span
