Std.LruCache.keys

fn

This is a callable function.

What it does

Every key, least recently used first.

The order entries would be discarded in, which is the useful direction to

read a cache in when deciding whether its capacity is right.

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.
