Struct ByteRange 

pub struct ByteRange {
    pub start: usize,
    pub end: usize,
}

A half-open byte range [start, end) in the source text.

Fields

start: usize

Inclusive start byte offset.

end: usize

Exclusive end byte offset.

Implementations

impl ByteRange

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

Create a byte range.

pub fn empty() -> Self

The empty range at offset 0.

pub fn len(&self) -> usize

Length of the range in bytes.

pub fn is_empty(&self) -> bool

Whether the range is empty.

pub fn union(self, other: ByteRange) -> ByteRange

Merge two ranges into the smallest containing range.

pub fn contains(&self, offset: usize) -> bool

Whether this range contains a byte offset.

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

Extract the covered slice from a source string.

Trait Implementations

impl Clone for ByteRange

fn clone(&self) -> ByteRange

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ByteRange

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

Formats the value using the given formatter.

impl Display for ByteRange

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

Formats the value using the given formatter.

impl Hash for ByteRange

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 ByteRange

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