Struct Pos 

pub struct Pos {
    pub offset: usize,
    pub line: usize,
    pub col: usize,
}

Position in an input buffer or stream.

Fields

offset: usize

Zero-based byte offset from the start of the stream.

The first byte in the stream has offset zero, the second offset one, and so on.

line: usize

One-based line offset from the start of the stream.

The first byte in the stream is on line one, the first byte following the first line breaking sequence is on line two, and so on. One-based indexing is used for line because line numbers are primarily for consumption by humans, as opposed to byte offsets, which are primarily for consumption by computers.

col: usize

One based column offset from the start of the line, where columns are measured in characters. One-based indexing is used for col because column numbers are primarily for consumption by humans, as opposed to byte offsets, which are primarily for consumption by computers.

The first byte in the stream is at col one, and whenever the line number is incremented, the first byte on the next line is at col one. Each column number increment corresponds to a full valid UTF-8 character.

Note that the JSON spec only allows multi-byte UTF-8 within string values. Outside of strings, every one byte always equals one column; but inside a string, a valid two-, three-, or four-byte UTF-8 sequence will only increment the column count by 1.

Implementations

impl Pos

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

Creates a new Pos.

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 Ord for Pos

fn cmp(&self, other: &Pos) -> 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 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 PartialOrd for Pos

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