Struct Pos 

pub struct Pos {
    pub offset: usize,
    pub row: Row,
    pub col: Col,
}

A position in some source code string. Positions save the offset, the row and the column. That means that a position is only valid for a specific source code string.

Fields

offset: usize

Starts at 0.

row: Row

Starts at 1.

col: Col

Starts at 1.

Implementations

impl Pos

pub const fn start() -> Self

Creates a new position at the start of source code.

pub const fn right(self) -> Self

Returns this position, one character to the right.

pub const fn down(self) -> Self

Returns this position, one line down, and with the column reset to 1.

Trait Implementations

impl Clone for Pos

fn clone(&self) -> Pos

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Pos

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

Formats the value using the given formatter.

impl Default for Pos

fn default() -> Self

Returns the “default value” for a type.

impl Display for Pos

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

Formats the value using the given formatter.

impl Hash for Pos

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 PartialEq for Pos

fn eq(&self, other: &Pos) -> 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 Copy for Pos

impl Eq for Pos
