§readput
Fast and easy stdin input parsing for competitive programming in rust.
§Usage
Note: The inputs can be on the same line, or not, it doesn’t make a difference. They are separated by spaces or line breaks. Excess inputs are getting cached for the next read() call.
All types need to implement FromStr and Debug.
§Create a Scanner
Create a new Scanner. (Only ASCII support for now)
use readput::AsciiScanner;
use readput::Scanner;
let mut cin = AsciiScanner::new();§Read a single value
Note: They have to impl. FromStr and Debug.
let v = read!(cin, i128);§Read a tuple
let (a, b, c) = read!(cin, (String, i128, u32));
let (d, e) = read!(cin, (i32, i32));§Read a vector of tuples
Read a vector of tuples. 3 is the number of tuples in the vector to read.
let vec = read_vec!(cin, 3, (u32, String));§Read a vector of single values
Read a vector of single values. 3 is the number of elements to read. Note: They also have to impl. FromStr and Debug.
let vec: Vec<u32> = read_vec!(cin, 3, u32);§Iterate over input
Iterate over input. This will iterate forever. (Blocks until new input is entered).
for (a, b) in iter!(cin, (String, u32)) {
println!("{} {}", a, b);
}
