Std.LruCache.get

fn

This is a callable function.

What it does

The value stored under a key, and the cache with that key marked as used.

Both, because a read is what a recency order is about: taking the value

without recording that it was taken would let an entry the program relies on

be discarded as unused. A caller that genuinely only wants to look — a

diagnostic, a report — should use peek.

Read the signature

• The text after the name is the type checked by Pudu.
• Read arrows from left to right: inputs come first, and the final type is returned.
• & borrows a value for this call instead of moving or copying it.
• Names inside [ ] are type arguments, such as the item type held by a collection.
• Option holds Some(value) or None when no value is available.
