Struct Var

pub struct Var<T>(/* private fields */);

a variable stored on the filesystem (very secure 🔐)

Implementations

impl<T> Var<T>

pub fn new(name: &'static str) -> Self

create a var

impl<T: Serialize> Var<T>

pub fn set(&self, v: &T)

interior mutability!

let x = def!(x = 5u8);
x.set(&3u8);

impl<T: DeserializeOwned> Var<T>

pub fn get(&self) -> T

procure the stored variable

let y = def!(y = 5u8);
assert_eq!(y.get(), 5u8);
