[−][src]Struct rosy::Range
An instance of Ruby's Range
type.
This type supports being instantiated from Range
, RangeInclusive
,
and RangeTo
.
a..b
and a...b
versus a..b
and a..=b
In Rust (and many other languages), a..b
denotes an inclusive range.
However, in Ruby this syntax denotes an exclusive range.
In Rust, a..=b
denotes an exclusive range whereas in Ruby, ...
denotes
an inclusive range.
Examples
An exclusive range can be instantiated quite simply:
use rosy::{Range, Integer, Object}; let range = Range::<Integer>::new(0..10).unwrap(); assert_eq!(range.to_s(), "0...10");
The start and end bounds can be retrieved via into_bounds
:
use std::ops::Bound; let range = Range::<Integer>::new(1..=10).unwrap(); let (start, end) = range.into_bounds(); assert_eq!(start, 1); assert_eq!(end, Bound::Included(Integer::from(10)));
Methods
impl Range
[src]
pub fn from_bounds(
start: AnyObject,
end: AnyObject,
exclusive: bool
) -> Result<Self>
[src]
start: AnyObject,
end: AnyObject,
exclusive: bool
) -> Result<Self>
Creates a new instance from the given bounds, returning an exception if one is raised.
If end
is nil
, an infinite (unbounded) range is produced.
pub unsafe fn from_bounds_unchecked(
start: AnyObject,
end: AnyObject,
exclusive: bool
) -> Self
[src]
start: AnyObject,
end: AnyObject,
exclusive: bool
) -> Self
Creates a new instance from the given bounds, without checking for exceptions.
If end
is nil
, an infinite (unbounded) range is produced.
Safety
An exception may be raised if start
and end
cannot be compared.
impl<S: Object, E: Object> Range<S, E>
[src]
pub fn new<R, A, B>(range: R) -> Result<Self> where
R: IntoBounds<A, B>,
A: Into<S>,
B: Into<E>,
[src]
R: IntoBounds<A, B>,
A: Into<S>,
B: Into<E>,
Creates a new instance from range
, returning an exception if one is
raised.
pub unsafe fn new_unchecked<R, A, B>(range: R) -> Self where
R: IntoBounds<A, B>,
A: Into<S>,
B: Into<E>,
[src]
R: IntoBounds<A, B>,
A: Into<S>,
B: Into<E>,
Creates a new instance from range
, without checking for exceptions.
Safety
An exception may be raised if S
and E
cannot be compared.
pub fn into_any_range(self) -> Range
[src]
Returns a range over AnyObject
s.
pub fn into_bounds(self) -> (S, Bound<E>)
[src]
