Disk: serde + directories + a whole bunch of file formats as Traits.
This crate is for (de)serializing to/from various file formats (provided by serde) to/from disk locations that follow OS-specific specifications/conventions (provided by directories).
All errors returned are of type anyhow::Error.
| File Format | Feature flag to enable |
|-------------|------------------------|
| Bincode | bincode
| JSON | json
| TOML | toml
| YAML | yaml
| Pickle | pickle
| MessagePack | messagepack
| BSON | bson
| Plain Text | plain
Defining our struct, State:
```rust
use disk::prelude::*; // Necessary imports to get things working.
use disk::{Toml,toml_file}; // <- TOML trait & macro.
use serde::{Serialize, Deserialize};
// To make this struct a file, use the following macro: // // |- 1. The file format used will be TOML. // | // | |- 2. The struct "State" will be used. // | | // | | |- 3. It will be saved in the OS Data directory. // | | | // | | | |- 4. The main project directory is called "MyProject". // | | | | // | | | | |- 6. It won't be in any sub-directories. // | | | | | // | | | | | |- 7. The file name will be "state.toml". // v v v v v v toml_file!(State, Dir::Data, "MyProject", "", "state");
serde.struct State { string: String, number: u32, } ```
Saving State to disk:
```rust
let state = State { string: "Hello".to_string(), number: 0 };
// This writes to ~/.local/share/myproject/state.toml
state.write().unwrap();
```
Creating a State from disk:
rust
// This reads from `~/.local/share/myproject/state.toml`
let state = State::from_file().unwrap();
