I am learning rust, and wondering if rust's std library, i/o and verbose syntax will get better and rich like c++ for competitive programming in future.

I have actually won a programming competition using Rust so I think it's quite usable for that. Admittedly this particular competition lasted several months so it was more of a marathon than a sprint. Short competitions might have different trade-offs. I did a bunch of competitive programming in sh…

Some regionals of ICPC allow you to use Rust, and I have previously been on the winning team of such a ICPC regional, while primarily using Rust for our solutions.

Probably not. Rust is always trying to improve, make it quicker to develop programs, compile faster, etc. However, Rust is focused on safety, correctness, performance, and low-level control. When it can't have it all, Rust will choose to focus towards these goals. syntax that is quick to write m…

Since you mention IO, here's the best way to make IO convenient for competitive programming in Rust: use std::str::FromStr; use std::str::SplitAsciiWhitespace; use std::io::Read; struct IO<'a>(SplitAsciiWhitespace<'a>); impl<'a> IO<'a> { fn next<T: FromStr>(&mut self) -> T { self.0.nex…

I do hope that "competitive programming", whatever that is supposed to mean, does not become the driving force behind Rust's evolution. The issue of the size of the standard library has been discussed here many times. It is kept small deliberately for god reasons. I happen to think they are good re…

The "rich std" idea is a red herring. There is no reason programming competition platforms have to restrict your dependencies to std. Some do, but that's just laziness or lack of knowledge on the part of the organizers and the right solution is to allow a few other crates in the competition rather t…

[image] ZiCog: But on occasion I have found myself in coding challenges that required banning the use of non-standard libs. Basically because if the challenge is "do X in your favourite language Y" and if there is a library out there that does X then there is no challenge. I did not say they …

[image] priyanshu00001: verbose syntax will get better and rich like c++ for competitive programming in future. Rust's syntax really isn't materially more verbose than C++'s. Usually the bigger problem is the programming environments, not Rust itself. If they don't let you use regex, care a…

Will rust be good for competitive programming?

Sounds reasonable.
