Struct Span 

pub struct Span {
    pub start: usize,
    pub end: usize,
    pub style: Style,
}

A marked-up region in some text.

Fields

start: usize

end: usize

style: Style

Implementations

impl Span

pub fn new(start: usize, end: usize, style: Style) -> Self

Create a new Span covering byte range [start, end) with a given style.

pub fn is_empty(&self) -> bool

Check if this span is non-empty.

pub fn split(&self, offset: usize) -> (Self, Option<Self>)

Split a span at the given offset, producing two spans. The first covers [start, offset), the second [offset, end).

pub fn move_by(&self, offset: isize) -> Self

Move start and end by a given offset.

pub fn right_crop(&self, offset: usize) -> Self

Crop the span end to not exceed offset.

Trait Implementations

impl Clone for Span

fn clone(&self) -> Span

Returns a duplicate 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: &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.
