Struct Position 

pub struct Position {
    pub line: u32,
    pub column: u32,
}

Position.

Positions are used to represent a specific point in a text file, typically for error reporting or debugging purposes. They are defined by a line and column number, both of which use 0-based indexing, which is what the Language Server Protocol and Source Maps require.

However, when printing via fmt::Display, the line and column numbers are formatted as 1-based indices, which is what most editors use.

Fields

line: u32

Line number, 0-based.

column: u32

Column number, 0-based.

Implementations

impl Position

pub fn new(line: u32, column: u32) -> Self

Creates a position with the given line and column numbers.

Examples

use zrx_diagnostic::location::Position;

// Create position
let position = Position::new(0, 0);

Trait Implementations

impl Clone for Position

fn clone(&self) -> Position

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Position

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

Formats the value using the given formatter.

impl Display for Position

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

Formats the position for display.

impl From<(u32, u32)> for Position

fn from((line, column): (u32, u32)) -> Self

Creates a position from a tuple.

Examples

use zrx_diagnostic::location::Position;

// Create position from tuple
let position: Position = (0, 0).into();

impl Ord for Position

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

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

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

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Position

fn eq(&self, other: &Position) -> 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 PartialOrd for Position

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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