Enum LineSpec 

pub enum LineSpec {
    Single(usize),
    Range(usize, usize),
}

A line specification: either a single line or a range.

Variants

Single(usize)

Single line number.

Range(usize, usize)

Range of lines (inclusive).

Implementations

impl LineSpec

pub fn parse(s: &str) -> Result<Self>

Parse a line spec string.

Examples

let spec = LineSpec::parse("42").unwrap();
let spec = LineSpec::parse("10-20").unwrap();

pub fn contains(&self, line: usize) -> bool

Check if this spec contains the given line number.

pub fn start(&self) -> usize

Get the starting line number.

Trait Implementations

impl Clone for LineSpec

fn clone(&self) -> LineSpec

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LineSpec

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

Formats the value using the given formatter.

impl PartialEq for LineSpec

fn eq(&self, other: &LineSpec) -> 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.
