Struct SourcePosition 

pub struct SourcePosition {
    pub offset: usize,
    pub line: usize,
    pub column: usize,
}

A source position with both byte offset and line/column information.

Fields

offset: usize

Byte offset from the start of the file.

line: usize

1-based line number.

column: usize

1-based column number.

Implementations

impl SourcePosition

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

Create a source position.

pub fn origin() -> Self

The origin position (offset 0, line 1, col 1).

pub fn advance_col(self, bytes: usize) -> Self

Advance by one character (non-newline).

pub fn advance_line(self, bytes: usize) -> Self

Advance to the next line.

pub fn is_before(&self, other: &SourcePosition) -> bool

Check if this position is before another.

pub fn is_after(&self, other: &SourcePosition) -> bool

Check if this position is after another.

Trait Implementations

impl Clone for SourcePosition

fn clone(&self) -> SourcePosition

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SourcePosition

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

Formats the value using the given formatter.

impl Display for SourcePosition

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

Formats the value using the given formatter.

impl Hash for SourcePosition

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 SourcePosition

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

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

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