|

|
|
A macro for declaring lazily evaluated statics.
|
|||
|
|
|
|||
|
|
Using this macro, it is possible to have `static`s that require code to be
|
|||
|
|
executed at runtime in order to be initialized.
|
|||
|
|
This includes anything requiring heap allocations, like vectors or hash maps,
|
|||
|
|
as well as anything that requires function calls to be computed.
|
|||
|
|
|
|||
|
|
# Syntax
|
|||
|
|
|
|||
|
|
```ignore
|
|||
|
|
lazy_static! {
|
|||
|
|
[pub] static ref NAME_1: TYPE_1 = EXPR_1;
|
|||
|
|
[pub] static ref NAME_2: TYPE_2 = EXPR_2;
|
|||
|
|
...
|
|||
|
|
[pub] static ref NAME_N: TYPE_N = EXPR_N;
|
|||
|
|
}
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
Attributes (including doc comments) are supported as well:
|
|||
|
|
|
|||
|
|
```rust
|
|||
|
|
use lazy_static::lazy_static;
|
|||
|
|
|
|||
|
|
# fn main() {
|
|||
|
|
lazy_static! {
|
|||
|
|
/// This is an example for using doc comment attributes
|
|||
|
|
static ref EXAMPLE: u8 = 42;
|
|||
|
|
}
|
|||
|
|
# }
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
# Semantics
|
|||
|
|
|
|||
|
|
For a given `static ref NAME: TYPE = EXPR;`, the macro generates a unique type that
|
|||
|
|
implements `Deref<TYPE>` and stores it in a static with name `NAME`. (Attributes end up
|
|||
|
|
attaching to this type.)
|
|||
|
|
|
|||
|
|
On first deref, `EXPR` gets evaluated and stored internally, such that all further derefs
|
|||
|
|
can return a reference to the same object. Note that this can lead to deadlocks
|
|||
|
|
if you have multiple lazy statics that depend on each other in their initialization.
|
|||
|
|
|
|||
|
|
Apart from the lazy initialization, the resulting "static ref" variables
|
|||
|
|
have generally the same properties as regular "static" variables:
|
|||
|
|
|
|||
|
|
- Any type in them needs to fulfill the `Sync` trait.
|
|||
|
|
- If the type has a destructor, then it will not run when the process exits.
|
|||
|
|
|
|||
|
|
# Example
|
|||
|
|
|
|||
|
|
Using the macro:
|
|||
|
|
|
|||
|
|
```rust
|
|||
|
|
use lazy_static::lazy_static;
|
|||
|
|
use std::collections::HashMap;
|
|||
|
|
|
|||
|
|
lazy_static! {
|
|||
|
|
static ref HASHMAP: HashMap<u32, &'static str> = {
|
|||
|
|
let mut m = HashMap::new();
|
|||
|
|
m.insert(0, "foo");
|
|||
|
|
m.insert(1, "bar");
|
|||
|
|
m.insert(2, "baz");
|
|||
|
|
m
|
|||
|
|
};
|
|||
|
|
static ref COUNT: usize = HASHMAP.len();
|
|||
|
|
static ref NUMBER: u32 = times_two(21);
|
|||
|
|
}
|
|||
|
|
|
|||
|
|
fn times_two(n: u32) -> u32 { n * 2 }
|
|||
|
|
|
|||
|
|
fn main() {
|
|||
|
|
println!("The map has {} entries.", *COUNT);
|
|||
|
|
println!("The entry for `0` is \"{}\".", HASHMAP.get(&0).unwrap());
|
|||
|
|
println!("A expensive calculation on a static results in: {}.", *NUMBER);
|
|||
|
|
}
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
# Implementation details
|
|||
|
|
|
|||
|
|
The `Deref` implementation uses a hidden static variable that is guarded by an atomic check on each access.
|
|||
|
|
|
|||
|
|
# Cargo features
|
|||
|
|
|
|||
|
|
This crate provides one cargo feature:
|
|||
|
|
|
|||
|
|
- `spin_no_std`: This allows using this crate in a no-std environment, by depending on the standalone `spin` crate.
