QUESTION
I am trying to write a very basic crawler. After receiving an HTTP response, I am using the select.rs crate to extract the URLs from the body for further crawling.
How can I extract these URLs from from the "document" which is the "body" part of the HTTP response using the "for-iteration"?
...ANSWER
Answered 2018-Feb-27 at 17:54I assume you copied the Attr("id", "hmenus")
from some example code. This is a filter predicate that matches an HTML node containing attribute id="hmenus"
. Your example page um.ac.ir does not contain any nodes with attribute id="hmenus"
. If you want the crawler to find all nodes on the page, the filter predicate would be Name("a")
.
QUESTION
I am attempting to add a GUI to a small project of mine using Conrod. I have managed to work my way down to 3 compilation errors:
...ANSWER
Answered 2018-Jan-23 at 07:00I believe this is a misconception about the module structure of conrod
and glium
.
The conrod crate has a number of backend modules, containing utility functions for each of the different backends. conrod::backend::glium
is this module for glium, and it contains structures and things useful for using conrod with glium.
In your case, however, I think you mistook this module for glium
itself.
glium
is a separate crate from conrod, and you'll need to depend on it much like you depend on glutin
. glium
does indeed have a glium::conrod
property, so if you do pull it in with extern crate glium;
rather than using conrod::backend::glium
, it should "just work"!
You'll need to add some line glium = 0.x
in your Cargo.toml
as well, but that should be trivial.
