Struct Marker 

pub struct Marker {
    pub index: usize,
    pub line: usize,
    pub column: usize,
}

A location in the source string.

Fields

index: usize

Offset in bytes from the start of the source string.

line: usize

Line number in the source string.

column: usize

Column number in the source string.

Implementations

impl Marker

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

Create a new location.

pub const fn start() -> Self

Create a location pointing to the start of the source string.

pub const fn zero() -> Self

Create an empty location.

pub fn line(&self) -> usize

Return the line number of this location.

pub fn column(&self) -> usize

Return the column number of this location.

pub fn index(&self) -> usize

Return the index of this location.

Trait Implementations

impl Clone for Marker

fn clone(&self) -> Marker

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Marker

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

Formats the value using the given formatter.

impl Default for Marker

fn default() -> Self

Returns the “default value” for a type.

impl Display for Marker

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

Formats the value using the given formatter.

impl From<Marker> for Span

fn from(marker: Marker) -> Self

Converts to this type from the input type.

impl Ord for Marker

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

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

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