Struct Index 

pub struct Index { /* private fields */ }

An Index struct holds information about source positions.

Implementations

impl Index

pub fn new(start: usize, stop: usize) -> Self

Create a new Index with start and stop.

pub fn start(&self) -> usize

A Start position of the index.

pub fn stop(&self) -> usize

A Stop position of the index.

pub fn bytes<'a>(&self, source: &'a str) -> &'a [u8]

Returns the bytes of the index from the source.

pub fn str<'a>(&self, source: &'a str) -> &'a str

Returns the str of the index from the source.

Safety

This method does not check the validity of UTF-8 boundaries.

pub fn is_empty(&self) -> bool

Returns true if the index is empty, otherwise false.

pub fn with_start(&self, v: usize) -> Index

Returns a new Index with same value except stop.

pub fn with_stop(&self, v: usize) -> Index

Returns a new Index with same value except stop.

pub fn len(&self) -> usize

Returns the length of the index.

Trait Implementations

impl Clone for Index

fn clone(&self) -> Index

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Index

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

Formats the value using the given formatter.

impl From<(usize, usize)> for Index

fn from((start, stop): (usize, usize)) -> Self

Converts to this type from the input type.

impl From<Index> for Segment

fn from(index: Index) -> Self

Converts to this type from the input type.

impl From<Index> for Value

fn from(index: Index) -> Self

Converts to this type from the input type.

impl From<Segment> for Index

fn from(segment: Segment) -> Self

Converts to this type from the input type.

impl Hash for Index

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 Index

fn eq(&self, other: &Index) -> 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.
