Struct IntRange 

pub struct IntRange {
    pub start: i64,
    pub end: i64,
    pub step: i64,
}

A single contiguous range of integers with a step.

Fields

start: i64

end: i64

step: i64

Implementations

impl IntRange

pub fn new(start: i64, end: i64, step: i64) -> Result<Self, ExpressionError>

Create a range, normalizing descending ranges to ascending form. After construction, start <= end and step > 0 always hold.

pub fn len(&self) -> usize

Number of integers in this range.

pub fn is_empty(&self) -> bool

Returns true if the range contains no elements.

pub fn contains(&self, value: i64) -> bool

Test whether value is a member of this range.

pub fn iter(&self) -> impl Iterator<Item = i64> + '_

Iterate over all values in ascending order.

pub fn get(&self, index: usize) -> Option<i64>

Get element by zero-based index, or None if out of bounds.

Trait Implementations

impl Clone for IntRange

fn clone(&self) -> IntRange

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IntRange

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for IntRange

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for IntRange

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

Formats the value using the given formatter.

impl Hash for IntRange

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 IntRange

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
