[−][src]Struct abi_stable::lazy_static_ref::LazyStaticRef
A late-initialized static reference.
Methods
impl<T> LazyStaticRef<T>[src]
pub const fn new() -> Self[src]
Constructs the late initialized static reference, in an uninitialized state.
pub fn try_init<F, E>(&self, initializer: F) -> Result<&'static T, E> where
F: FnOnce() -> Result<&'static T, E>, [src]
F: FnOnce() -> Result<&'static T, E>,
Lazily initializes the reference with initializer,
returning the reference if either it was already initialized,or
if initalizer returned Ok(..).
If initializer returns an Err(...) this returns the error and
allows the reference to be initializer later.
If initializer panics,the panic is propagated,
and the reference can be initalized later.
pub fn init<F>(&self, initializer: F) -> &'static T where
F: FnOnce() -> &'static T, [src]
F: FnOnce() -> &'static T,
Lazily initializes the reference with initializer,
returning the reference if either it was already initialized,or
once initalizer returns the reference.
If initializer panics,the panic is propagated,
and the reference can be initalized later.
pub fn get(&self) -> Option<&'static T>[src]
Returns Some(x:&'static T) if the reference was initialized,otherwise returns None.
