Struct Location

pub struct Location {
    pub source: Source,
    pub offset: usize,
}

A single location within a source file, expressed as a byte offset.

Fields

source: Source

offset: usize

Implementations

impl Location

pub fn new(source: Source, offset: usize) -> Location

Create a new location.

pub fn with_line_and_column( source: Source, line: usize, column: usize, ) -> Location

Create a new location given a human-readable line and column.

pub fn iter<'a>(self, content: &'a Rc<dyn SourceContent>) -> Box<CharIter<'a>>

Obtain an iterator into the source file at this location.

pub fn human(self) -> (usize, usize, usize)

Determine the line and column information at this location.

Returns a tuple (line, column, line_offset).

pub fn human_line(self) -> usize

Determine the line at this location.

pub fn human_column(self) -> usize

Determine the column at this location.

pub fn human_line_offset(self) -> usize

Determine the line offset at this location.

Trait Implementations

impl Clone for Location

fn clone(&self) -> Location

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Location

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

Formats the value using the given formatter.

impl From<Location> for Span

fn from(l: Location) -> Span

Converts to this type from the input type.

impl Hash for Location

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 Location

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

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

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