Struct swiss_army_knife::StaticInitializedOnce
source · [−]pub struct StaticInitializedOnce<Value: Sized> { /* private fields */ }Expand description
A wrapper type to use with mutable static fields where one does not want the overhead and inflexibility of lazy_static!.
Implementations
sourceimpl<Value: Sized> StaticInitializedOnce<Value>
impl<Value: Sized> StaticInitializedOnce<Value>
sourcepub const fn uninitialized() -> Self
pub const fn uninitialized() -> Self
Uninitialized value suitable for use in a static.
sourcepub fn initialize_once(&mut self, value: Value) -> &mut Value
pub fn initialize_once(&mut self, value: Value) -> &mut Value
Initialize once.
Not thread safe; indeed, may panic in debug mode.
sourcepub fn value_mut(&mut self) -> &'static mut Value
pub fn value_mut(&mut self) -> &'static mut Value
Value.
