Allow inserting a function on any type in a call chain:
any_type
.fun(|o| do_something_with(o))
.other_things();
More detailled example:
use {
have::Fun,
itertools::*,
};
fn analyze(log_lines: Vec<LogLine>) {
log_lines
.iter()
.into_group_map_by(|ll| ll.remote_addr)
.fun(|g| println!("{} distinct remote_addresses", g.len()))
.into_iter()
.sorted_by_key(|e| Reverse(e.1.len()))
.take(3)
.for_each(|e| println!("{} hits by remote addresse {}", e.1.len(), e.0));
}
Removal of this crate
I just found out there was already another crate doing exactly the same thing the same way, with added features: tap.
I see no reason not to use the oldest crate. Unless there's an unexpected problem with the tap crate, I suggest you choose it over mine when building a new thing.
Usage:
[dependencies]
have = "0.1"
lib.rs
:
Make any type have some fun.
This is convenient when you want to insert some function call in a chain without reordering it or create intermediate variables.
use have::Fun;
let sum = [1, 2, 3]
.fun(|v| println!("v is size {}", v.len()))
.iter()
.sum::<usize>();
