Struct line_numbers::LinePositions

pub struct LinePositions { /* private fields */ }

A struct for efficiently converting absolute string positions to line-relative positions.

Implementations

impl LinePositions

pub fn from_offset(&self, offset: usize) -> LineNumber

Return the line number containing this offset.

Panics

Panics if offset is out of bounds.

pub fn from_region( &self, region_start: usize, region_end: usize ) -> Vec<SingleLineSpan>

Convert this region into line spans. If the region includes a newline, the vec will contain multiple items.

Panics

Panics if region_start or region_end are out of bounds.

pub fn from_region_relative_to( &self, start: SingleLineSpan, region_start: usize, region_end: usize ) -> Vec<SingleLineSpan>

Trait Implementations

impl Debug for LinePositions

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<&str> for LinePositions

fn from(s: &str) -> Self

Converts to this type from the input type.
