Struct Span

struct Span {
    range: Range<usize>,
    data: Rc<[u8]>,
    committed: bool,
}

Data that should replace a particular range of the original.

Fields

range: Range<usize>

Span of the parent data to be replaced, inclusive of the start, exclusive of the end.

data: Rc<[u8]>

New data to insert at the start position of the original data.

committed: bool

Whether this data is committed or provisional.

Implementations

impl Span

fn new(range: Range<usize>, data: &[u8]) -> Self

fn is_insert(&self) -> bool

Returns true if and only if this is a “pure” insertion, i.e. does not remove any existing data.

The insertion point is the start position of the range.

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 PartialEq for Span

fn eq(&self, other: &Self) -> bool

Returns true if and only if this Span and other have the same range and data, regardless of committed status.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
