Enum Selector 

pub enum Selector {
    All,
    LineNumbers(Vec<LineSpec>),
    Positions(Vec<Position>),
}

A selector specifying which lines/positions to extract.

Variants

All

Select all lines (no selector provided).

LineNumbers(Vec<LineSpec>)

Select specific line numbers and/or ranges.

Positions(Vec<Position>)

Select specific positions (line:column).

Implementations

impl Selector

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

Parse a selector string.

Examples

use sel::selector::Selector;

let sel = Selector::parse("42").unwrap();
let sel = Selector::parse("10-20").unwrap();
let sel = Selector::parse("1,5,10-15").unwrap();
let sel = Selector::parse("23:260").unwrap();

pub fn normalize(&self) -> Self

Normalize the selector by merging adjacent/range specs.

pub fn is_positional(&self) -> bool

Returns true if this is a positional selector.

Trait Implementations

impl Clone for Selector

fn clone(&self) -> Selector

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Selector

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

Formats the value using the given formatter.

impl PartialEq for Selector

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

impl Eq for Selector
