Struct Span 

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

A style applied to a byte range [start, end) of a Text’s plain string. Mirrors rich.text.Span.

The style may be a name rather than a resolved Style; see StyleType. Names are resolved when the text is rendered, against the theme of whichever console renders it.

Fields

start: usize

end: usize

style: StyleType

Implementations

impl Span

pub fn new(start: usize, end: usize, style: impl Into<StyleType>) -> Self

A span of style over [start, end).

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

Split at offset, when it falls inside the span. Port of Span.split.

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

The span moved by offset. Port of Span.move.

Panics

When the move would take an offset below zero.

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

The span cropped to end at offset. Port of Span.right_crop.

pub fn extend(&self, cells: usize) -> Span

The span with its end moved cells further. Port of Span.extend.
