Struct SourcePos 

pub struct SourcePos {
    pub line: usize,
    pub col: usize,
}

A line/column position in source text (1-indexed).

Fields

line: usize

1-indexed line number.

col: usize

1-indexed column number (byte offset within the line).

Implementations

impl SourcePos

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

Construct a new SourcePos.

pub fn start() -> Self

The “beginning of file” position.

pub fn advance_col(&self) -> Self

Advance by one ASCII character (no newline).

pub fn advance_line(&self) -> Self

Advance to the next line (column resets to 1).

pub fn same_line(&self, other: &SourcePos) -> bool

true if other is on the same line as self.

Trait Implementations

impl Clone for SourcePos

fn clone(&self) -> SourcePos

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SourcePos

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

Formats the value using the given formatter.

impl Display for SourcePos

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

Formats the value using the given formatter.

impl Hash for SourcePos

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 SourcePos

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

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

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