Struct Range 

pub struct Range {
    pub start: u32,
    pub end: u32,
}

Range type

Essentially this is just a std::ops::Range<u32>, but with convenient implementations.

Note that we consider u32 large enough for any text we wish to display and the library is too complex to be useful on 16-bit CPUs, so using u32 makes more sense than usize.

Fields

start: u32

end: u32

Implementations

impl Range

pub fn start(self) -> usize

The start, as usize

pub fn end(self) -> usize

The end, as usize

pub fn is_empty(self) -> bool

True if the range is empty

pub fn len(self) -> usize

The number of iterable items, as usize

pub fn includes(self, value: usize) -> bool

True if the given value is contained, inclusive of end points

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

Convert to a standard range

pub fn iter(self) -> impl Iterator<Item = usize>

Convert to usize and iterate

Trait Implementations

impl Clone for Range

fn clone(&self) -> Range

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Range

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

Formats the value using the given formatter.

impl Default for Range

fn default() -> Range

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Range

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<Range<u32>> for Range

fn from(range: Range<u32>) -> Range

Converts to this type from the input type.

impl From<Range<usize>> for Range

fn from(range: Range<usize>) -> Range

Converts to this type from the input type.

impl From<Range> for Range<usize>

fn from(range: Range) -> Range<usize>

Converts to this type from the input type.

impl Hash for Range

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<T> Index<Range> for [T]

type Output = [T]

The returned type after indexing.

fn index(&self, range: Range) -> &[T]

Performs the indexing (container[index]) operation.

impl Index<Range> for String

type Output = str

The returned type after indexing.

fn index(&self, range: Range) -> &str

Performs the indexing (container[index]) operation.

impl Index<Range> for str

type Output = str

The returned type after indexing.

fn index(&self, range: Range) -> &str

Performs the indexing (container[index]) operation.

impl<T> IndexMut<Range> for [T]

fn index_mut(&mut self, range: Range) -> &mut [T]

Performs the mutable indexing (container[index]) operation.

impl IndexMut<Range> for String

fn index_mut(&mut self, range: Range) -> &mut str

Performs the mutable indexing (container[index]) operation.

impl IndexMut<Range> for str

fn index_mut(&mut self, range: Range) -> &mut str

Performs the mutable indexing (container[index]) operation.

impl PartialEq for Range

fn eq(&self, other: &Range) -> 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 Range

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Range

impl Eq for Range

impl StructuralPartialEq for Range
