(Attributes end up\nattaching to this type.)\n\nOn first deref, `EXPR` gets evaluated and stored internally, such that all further derefs\ncan return a reference to the same object. Note that this can lead to deadlocks\nif you have multiple lazy statics that depend on each other in their initialization.\n\nApart from the lazy initialization, the resulting \"static ref\" variables\nhave generally the same properties as regular \"static\" variables:\n\n- Any type in them needs to fulfill the `Sync` trait.\n- If the type has a destructor, then it will not run when the process exits.\n\n# Example\n\nUsing the macro:\n\n```rust\n#[macro_use]\nextern crate lazy_static;\n\nuse std::collections::HashMap;\n\nlazy_static! {\n static ref HASHMAP: HashMap<u32, &'static str> = {\n let mut m = HashMap::new();\n m.insert(0, \"foo\");\n m.insert(1, \"bar\");\n m.insert(2, \"baz\");\n m\n };\n static ref COUNT: usize = HASHMAP.len();\n static ref NUMBER: u32 = times_two(21);\n}\n\nfn times_two(n: u32) -> u32 { n * 2 }\n\nfn main() {\n println!(\"The map has {} entries.\", *COUNT);\n println!(\"The entry for `0` is \\\"{}\\\".\", HASHMAP.get(&0).unwrap());\n println!(\"A expensive calculation on a static results in: {}.\", *NUMBER);\n}\n```\n\n# Implementation details\n\nThe `Deref` implementation uses a hidden static variable that is guarded by an atomic check on each access.\n\n# Cargo features\n\nThis crate provides one cargo feature:\n\n- `spin_no_std`: This allows using this crate in a no-std environment, by depending on the standalone `spin` crate.\n\n"]#![doc(html_root_url="https://docs.rs/lazy_static/1.4.0")]#![no_std]use crate::__cargo_equip::preludes::lazy_static::*;pub use crate::__cargo_equip::macros::lazy_static::*;#[path="inline_lazy.rs"]#[doc(hidden)]pub mod lazy{use crate::__cargo_equip::preludes::lazy_static::*;extern crate core;extern crate std;use self::std::prelude::v1::*;use self::std::cell::Cell;use self::std::hint::unreachable_unchecked;use self::std::sync::Once;#[allow(deprecated)]pub use self::std::sync::ONCE_INIT;pub struct Lazy<T:Sync>(Cell<Option<T> >,Once);impl<T:Sync>Lazy<T>{#[allow(deprecated)]pub const INIT:Self=Lazy(Cell::new(None),ONCE_INIT);#[inline(always)]pub fn get<F>(&'static self,f:F)->&T where F:FnOnce()->T,{self.1.call_once(| |{self.0.set(Some(f()));});unsafe{match*self.0.as_ptr(){Some(ref x)=>x,None=>{debug_assert!(false,"attempted to derefence an uninitialized lazy static.
