rustGenerator example in Rust
Generators are a powerful tool in Rust for creating iterators. Generators are functions that can be paused and resumed, allowing them to yield values one at a time.
Example code
fn generator() -> impl Iterator<Item = i32> {
let mut i = 0;
loop {
yield i;
i += 1;
}
}
Output example
0
1
2
3
...
Code explanation
fn generator() -> impl Iterator<Item = i32>
: This declares a function namedgenerator
that returns an iterator of typei32
.let mut i = 0
: This declares a mutable variablei
and initializes it to0
.yield i
: This pauses the function and returns the value ofi
.i += 1
: This incrementsi
by1
.loop { ... }
: This creates an infinite loop that will keep yielding values until it is manually stopped.
