Struct LazyData 

pub struct LazyData {
    pub initializer: Arc<Mutex<Option<ValueWord>>>,
    pub value: Arc<Mutex<Option<ValueWord>>>,
}

Lazy-initialized value — compute once, cache forever. The initializer closure runs at most once; subsequent accesses return the cached result.

Fields

initializer: Arc<Mutex<Option<ValueWord>>>

Closure that produces the value (None after initialization).

value: Arc<Mutex<Option<ValueWord>>>

Cached result (None until first access).

Implementations

impl LazyData

pub fn new(initializer: ValueWord) -> Self

pub fn is_initialized(&self) -> bool

Check if the value has been initialized.

Trait Implementations

impl Clone for LazyData

fn clone(&self) -> LazyData

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LazyData

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
