Struct ucglib::ast::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 Eq for Position

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

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

Performs the conversion.

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

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

Performs the conversion.

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

impl Ord for Position

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

This method returns an Ordering between self and other.

#[must_use]pub fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]pub fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]pub fn clamp(self, min: Self, max: Self) -> Self

Restrict a value to a certain interval.

impl PartialEq<Position> for Position

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

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Position) -> bool

This method tests for !=.

impl PartialOrd<Position> for Position

fn partial_cmp(&self, other: &Position) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

#[must_use]pub fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

#[must_use]pub fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

#[must_use]pub fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

#[must_use]pub fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
