Struct Position 

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

A position (line, column, byte offset) in the source text.

Lines and columns are 1-based; offset is a 0-based byte offset suitable for slicing the original source string.

Note: column is byte-based (not character-based), so for non-ASCII text the column value may be larger than the visible character count.

Fields

line: usize

1-based line number.

column: usize

1-based column number (byte-based, not character-based).

offset: usize

0-based byte offset in the source string.

Implementations

impl Position

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

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<(), Error>

Formats the value using the given formatter.

impl Default for Position

fn default() -> Position

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Position

fn deserialize<__D>( __deserializer: __D, ) -> Result<Position, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Position

Display implementation for user-friendly error messages

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

Formats the value using the given formatter.

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 Serialize for Position

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Position

impl Eq for Position
