Struct Position 

pub struct Position {
    pub file: Option<PathBuf>,
    pub line: usize,
    pub column: usize,
    pub offset: usize,
}

Represents a line and a column position in UCG code.

It is used for generating error messages mostly. Most all parts of the UCG AST have a positioned associated with them.

Fields

file: Option<PathBuf>

line: usize

column: usize

offset: usize

Implementations

impl Position

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

Construct a new Position.

pub fn with_file<P: Into<PathBuf>>(self, file: P) -> Self

Trait Implementations

impl Clone for Position

fn clone(&self) -> Position

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Position

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

Formats the value using the given formatter.

impl Display for Position

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

Formats the value using the given formatter.

impl<'a> From<&'a OffsetStrIter<'a>> for Position

fn from(s: &'a OffsetStrIter<'a>) -> Position

Converts to this type from the input type.

impl<'a> From<&'a Position> for Position

fn from(source: &'a Position) -> Self

Converts to this type from the input type.

impl<'a> From<&'a SliceIter<'a, Token>> for Position

fn from(source: &'a SliceIter<'a, Token>) -> Self

Converts to this type from the input type.

impl Hash for Position

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 Position

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

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

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