Struct Span 

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

Locate a byte range in the d2 source, convertible to both a model span and a miette span.

Fields

start: usize

end: usize

Implementations

impl Span

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

Create a new span from byte start up to byte end.

pub fn range(self) -> Range<usize>

Return the byte range the span covers.

impl Span for Span

type Context = ()

Extra context used in a span.

type Offset = usize

fn to_end(&self) -> Self

where Self: Sized,

fn union(&self, other: Self) -> Self

where Self::Context: PartialEq + Debug, Self::Offset: Ord, Self: Sized,
