Struct codespan::LineIndex

pub struct LineIndex(pub RawIndex);

A zero-indexed line offset into a source file

Methods

impl LineIndex

pub fn number(self) -> LineNumber

The 1-indexed line number. Useful for pretty printing source locations.

use codespan::{LineIndex, LineNumber};

assert_eq!(format!("{}", LineIndex(0).number()), "1");
assert_eq!(format!("{}", LineIndex(3).number()), "4");

pub fn to_usize(self) -> usize

Convert the index into a usize, for use in array indexing

Trait Implementations

impl Index for LineIndex

type Offset = LineOffset

impl Copy for LineIndex

impl PartialEq<LineIndex> for LineIndex

fn eq(&self, other: &LineIndex) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &LineIndex) -> bool

This method tests for !=.

impl Default for LineIndex

fn default() -> LineIndex

Returns the "default value" for a type.

impl Clone for LineIndex

fn clone(&self) -> LineIndex

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Ord for LineIndex

fn cmp(&self, other: &LineIndex) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl From<u32> for LineIndex

fn from(i: RawIndex) -> Self

Performs the conversion.

impl Eq for LineIndex

impl PartialOrd<LineIndex> for LineIndex

fn partial_cmp(&self, other: &LineIndex) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &LineIndex) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &LineIndex) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &LineIndex) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &LineIndex) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Add<LineOffset> for LineIndex

type Output = LineIndex

The resulting type after applying the + operator.

fn add(self, rhs: LineOffset) -> LineIndex

Performs the + operation.

impl AddAssign<LineOffset> for LineIndex

fn add_assign(&mut self, rhs: LineOffset)

Performs the += operation.

impl SubAssign<LineOffset> for LineIndex

fn sub_assign(&mut self, rhs: LineOffset)
