# FastInput - Read input, fast!
FastInput is aimed to simplify reading of known input from `stdin`,
mainly in a competetive programming environment. The crate exposes
the `FastInput` struct which contains methods for reading and parsing
line-based input. `FastInput` does no validation of the input and
uses unsafe operations and buffering to achieve great performance.
## Example
The following example creates a new `FastInput` and reads some input:
```rust
// Input:
// Hello!
// 12 2000
use fast_input::FastInput;
let mut input = FastInput::new();
// Must make into String as next_line returns a slice to the internal buffer
// and the second input line advances the internal buffer.
let first_line = input.next_line().to_owned();
// Type arguments can often be omitted as rust is awesome, specified here
// for clarity.
let (a, b): (u32, u32) = input.next_tuple();
println!("First line was: {}, a + b = {}", first_line, a + b);
// Read a line of integers and collect into a `Vec`
let numbers: Vec<u32> = input.next_as_iter().collect();
// `FastInput` contains methods to read up to quintuples
let (a, b, c, d, e) = input.next_quintuple();
let sum: 0i32 + a + b + c + d + e;
// Read all remaining lines and print them
while input.has_next_line() {
println!("{}", input.next_line());
}
```
