# filestruct
A Rust derive macro which permits reading struct values from a directory.
Not ready for production use, still in heavy development and many things are
not yet implemented or will unexpectedly blow up.
# Usage
```rust
use filestruct::FromDir;
#[derive(FromDir, Debug)]
struct Files {
capacity: u8,
energy_now: u64,
does_not_exist: Option<u64>,
#[filestruct(file = "energy_full")]
does_not_exist_but_renamed: Option<u64>,
}
fn main() {
let files = Files::from_dir("/sys/class/power_supply/BAT0");
println!("{:#?}", files);
}
```
Results in:
```rust
Ok(
Files {
capacity: 67,
energy_now: 38460000,
does_not_exist: None,
does_not_exist_but_renamed: Some(
56970000,
),
},
)
```
