Struct SubRange 

pub struct SubRange { /* private fields */ }

A non-empty range targeting a smaller part of a spanned section of text.

Implementations

impl SubRange

pub fn new(start: usize, end: usize) -> Option<Self>

Create a new sub-range. The given start and end must create a non-empty range.

If start or end are above a 2^32-1, they will be saturated.

pub fn to_relative(self) -> Range<usize>

Convert to a normal range relative to the spanned range.

pub fn to_absolute(self, offset: usize) -> Range<usize>

Convert to a normal range at an offset.

Trait Implementations

impl Clone for SubRange

fn clone(&self) -> SubRange

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for SubRange

impl Debug for SubRange

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

Formats the value using the given formatter.

impl Eq for SubRange

impl Hash for SubRange

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 SubRange

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