Struct LineAndColumn 

pub struct LineAndColumn {
    pub line: NonZeroUsize,
    pub column: NonZeroUsize,
}

A 1-indexed line and column location intended for usage in errors/warnings/lints/etc.

Both line and column are 1-indexed, as that is how most people think of lines and columns.

Example

assert_eq!("Beginning of &str: 1:1",format!("Beginning of &str: {}", LineAndColumn::new(1, 1).unwrap()));

Fields

line: NonZeroUsize

The 1-indexed line absolute position (i.e., relative to the start of a &str)

column: NonZeroUsize

The 1-indexed character absolute position (i.e., relative to the start of a &str)

Implementations

impl LineAndColumn

pub fn new(line: usize, column: usize) -> Option<Self>

Constructs at LineAndColumn if non-zero-index invariants, else None

pub const unsafe fn new_unchecked(line: usize, column: usize) -> Self

Constructs at LineAndColumn without verifying 1-indexed invariant (i.e. nonzero). This results in undefined behaviour if either line or column is zero.

Safety

Both line and column values must not be zero.

Trait Implementations

impl Clone for LineAndColumn

fn clone(&self) -> LineAndColumn

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LineAndColumn

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

Formats the value using the given formatter.

impl Display for LineAndColumn

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

Formats the value using the given formatter.

impl From<LineAndCharPosition> for LineAndColumn

fn from(_: LineAndCharPosition) -> Self

Converts to this type from the input type.

impl Hash for LineAndColumn

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for LineAndColumn

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

fn eq(&self, other: &LineAndColumn) -> 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 LineAndColumn

fn partial_cmp(&self, other: &LineAndColumn) -> 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.
