# Rust Icon Loader

A crate that loads and caches themed icons in 100% safe rust.

## Usage

Just add it to your `cargo.toml` file like this:
```
[dependencies]
icon-loader = "0.4"
```

## Cargo-Features

### Standard Features

* `kde`: Feature that lets you read the default system theme name from '~/.config/kdeglobals'.
* `gtk`: Feature that lets you read the default system theme name from '~/.config/gtk-3.0/settings.ini'.

### Additional Features

* `theme_error_log`: Feature that uses the [`log`](https://crates.io/crates/log) crate to log errors that occur while parsing icon themes. 

## Examples

* Using a global [`IconLoader`](IconLoader) object to load icons from the systems `hicolor` icon theme:
```rust
use icon_loader::icon_loader_hicolor;

if let Some(icon) = icon_loader_hicolor().load_icon("audio-headphones") {
    let path = icon.file_for_size(64).path();
}
```

* Loading icons from the default icon theme set in KDE:
```rust
use icon_loader::IconLoader;

let loader = IconLoader::new_kde().unwrap();

if let Some(icon) = loader.load_icon("audio-headphones") {
    let path = icon.file_for_size(64).path();
}
```

* Loading icons from a custom theme in a provided folder:
```rust
use icon_loader::IconLoader;

let mut loader = IconLoader::new();
loader.set_search_paths(&["path_to_your_icon_theme"]);
loader.set_theme_name_provider("name_of_your_icon_theme");
loader.update_theme_name();

if let Some(icon) = loader.load_icon("icon_name") {
    let path = icon.file_for_size(32).path();
}
```
