Unused import

[jethrogb]

Problem Description

This code:

#[macro_use] extern crate diesel_codegen;
#[macro_use] extern crate diesel;

table! (config ( key ) {
    key -> ::diesel::types::Text,
    value -> ::diesel::types::Binary,
});

#[derive(Queryable, Insertable, Identifiable, AsChangeset, Debug)]
#[table_name="config"]
#[primary_key(key)]
pub struct Config {
    pub key: String,
    pub value: Vec<u8>,
}

results in the following lints:

warning: unused import
 --> src/main.rs:4:1
  |
4 | / table! (config ( key ) {
5 | |     key -> ::diesel::types::Text,
6 | |     value -> ::diesel::types::Binary,
7 | | });
  | |___^
  |
  = note: #[warn(unused_imports)] on by default
  = note: this error originates in a macro outside of the current crate

Yeah, you can just do

key -> Text,
value -> Binary

if you're not using any use statement in the table! call, we stick a use diesel::types::* in there, hence the warning.

Cool, should've read the changelog better I suppose 😃
