appres

appres is a library for interacting with application resources.

Examples

Basic usage:

use appres::Resources;

let resources = Resources::new_app_relative_to_config("projectile").unwrap();

// Check if the projectile directory has a file named list.yaml.
assert!(!resources.has_file("list.yaml"));

// Check if the projectile directory has a directory named hello_world.
assert!(!resources.has_dir("hello_world"));

Features

This library also contains extended functionality for json, toml, and yaml files that are feature-gated.

• json_resources: Enabling this feature gives you extra methods (through the JsonResourcesExt trait) and extra functions for working with json files.
• toml_resources: Enabling this feature gives you extra methods (through the TomlResourcesExt trait) and extra functions for working with toml files.
• yaml_resources: Enabling this feature gives you extra methods (through the YamlResourcesExt trait) and extra functions for working with yaml files.

Examples

For example, if you enable the yaml_resources feature in Cargo.toml...

use appres::Resources;
use appres::yaml::YamlResourcesExt;

// Create a resources manager for the projectile directory in the config directory.
let resources = Resources::new_app_relative_to_config("projectile").unwrap();

// Create a list of strings.
let list = vec!["a".to_string(), "b".to_string(), "c".to_string()];

// Write the serialized list to list.yaml in the projectile directory of the config
// directory.
resources.save_to_yaml_file("list.yaml", &list).unwrap();

// Load the list from the file again.
let list_copy: Vec<String> = resources.load_from_yaml_file("list.yaml").unwrap();
assert_eq!(list, list_copy);

// Check for the presence of the list.yaml file
assert!(resources.has_file("list.yaml"));
