Struct codespan::ColumnIndex

pub struct ColumnIndex(pub RawIndex);

A zero-indexed column offset into a source file

Methods

impl ColumnIndex

pub fn number(self) -> ColumnNumber

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

use codespan::{ColumnIndex, ColumnNumber};

assert_eq!(format!("{}", ColumnIndex(0).number()), "1");
assert_eq!(format!("{}", ColumnIndex(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 ColumnIndex

type Offset = ColumnOffset

impl Copy for ColumnIndex

impl PartialEq<ColumnIndex> for ColumnIndex

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

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

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

This method tests for !=.

impl Default for ColumnIndex

fn default() -> ColumnIndex

Returns the "default value" for a type.

impl Clone for ColumnIndex

fn clone(&self) -> ColumnIndex

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Ord for ColumnIndex

fn cmp(&self, other: &ColumnIndex) -> 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 ColumnIndex

fn from(i: RawIndex) -> Self

Performs the conversion.

impl Eq for ColumnIndex

impl PartialOrd<ColumnIndex> for ColumnIndex

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

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

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

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

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

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

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

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

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

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

impl Add<ColumnOffset> for ColumnIndex

type Output = ColumnIndex

The resulting type after applying the + operator.

fn add(self, rhs: ColumnOffset) -> ColumnIndex

Performs the + operation.

impl AddAssign<ColumnOffset> for ColumnIndex

fn add_assign(&mut self, rhs: ColumnOffset)

Performs the += operation.

impl SubAssign<ColumnOffset> for ColumnIndex

fn sub_assign(&mut self, rhs: ColumnOffset)
