Input

These are the inputs you need to provide to implement Json.

Variable	Description	Related Trait Constant	Type	Example
$data	Identifier of the data to implement for		struct or enum	MyState
$dir	Which OS directory to use	Json::OS_DIRECTORY	Dir	Dir::Data
$project_directory	The name of the top project folder	Json::PROJECT_DIRECTORY	&str	"MyProject"
$sub_directories	(Optional) sub-directories before file	Json::SUB_DIRECTORIES	&str	"some/dirs"
$file_name	The file name to use	Json::FILE_NAME	&str	"state"

Example

use serde::{Serialize,Deserialize};
use disk::*;

json!(State, Dir::Data, "MyProject", "some/dirs", "state");
#[derive(Serialize,Deserialize)]
struct State {
    string: String,
    number: u32,
}
