Getting Started with Rust: Working with Files and Doing File I/O

WebChange the original field input type File to R. Correspondingly, the implementation part should also be changed: impl Lex {Added , indicating that the constraint of is Read, that is, the type R must support the Read trait. This is because the input.read() function is used in the read_char() method. Webuse std::io;fn main() {let mut input String::new();io::stdin().read_line(&mut input).unwrap();let ns: Vec input.trim().split( ).map( x x.parse().unwrap ... Weblet input = input :: (). get (); Rust can often work out the type. When this is the case you can skip explicitly stating the type. input (). get () The input () function uses a common pattern called the builder pattern. Many settings can be use by adding methods between input () and get () . Available methods can be found on the ... early childhood studies minor umd duluth
