Why does this Rust import need `self`? -


this question has answer here:

i have following set of imports @ top of program:

extern crate serde_bencode; extern crate serde; extern crate serde_bytes; extern crate url; extern crate url_serde;  use serde_bytes::bytebuf; use serde_bencode::de; use serde_bencode::error::result; use serde_bencode::error::{custom, invalidlength}; use self::url::{url};

this program does compile. however, don't understand why need write self on use self::url::{url}; line. none of other use statements need self - why url?

for context, snippet above file called file_reader.rs, in directory following structure:

roar/     file_reader.rs     main.rs     lib.rs

edit: noticed if add line extern crate url; lib.rs, don't need self; however, don't know why step necessary.

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
