Struct swiss_army_knife::StaticInitializedOnce[−][src]

pub struct StaticInitializedOnce<Value: Sized> { /* fields omitted */ }

A wrapper type to use with mutable static fields where one does not want the overhead and inflexibility of lazy_static!.

Implementations

impl<Value: Sized> StaticInitializedOnce<Value>[src]

pub const fn uninitialized() -> Self[src]

Uninitialized value suitable for use in a static.

pub fn initialize_once(&mut self, value: Value) -> &mut Value[src]

Initialize once.

Not thread safe; indeed, may panic in debug mode.

pub fn value(&self) -> &'static Value[src]

Value.

pub fn value_mut(&mut self) -> &'static mut Value[src]

Value.
