Gamo
Create a Range like struct of user define types for easy for loop. Gamo means range in Esperanto.
What is it?
Currently Rust does not have a stable API to create Range<T>
of user defined type T
. This crate provides a Range
like struct Gamo
that can be easily used with for-loops.
Usage
[dependencies]
gamo = "0.2.0"
The type T
used in Gamo<T>
must implement TryToNext
trait.
Example
use gamo::{Gamo, TryToNext};
#[derive(Debug, Clone, PartialEq, Eq, PartialOrd, Ord)]
struct TimeSlot(usize);
impl TryToNext for TimeSlot {
fn try_to_next(&self) -> Option<Self> {
Some(Self(self.0 + 1))
}
}
fn main() {
for t in Gamo::new(TimeSlot(0), TimeSlot(5)) {
println!("{:?}", t);
}
}
