pub struct Span { /* private fields */ }
Expand description
A position in the original source stream, used to render errors.
Implementations
sourceimpl Span
impl Span
sourcepub fn from_offset(offset: usize) -> Self
pub fn from_offset(offset: usize) -> Self
Construct a Span
from a byte offset in the source file.
sourcepub fn linecol_in(&self, text: &str) -> (usize, usize)
pub fn linecol_in(&self, text: &str) -> (usize, usize)
Returns the line/column information of this span within text
.
Line and column numbers are 0-indexed. User presentation is typically
1-indexed, but 0-indexing is appropriate for internal use with
iterators and slices.
