Module abstutil::collections [−][src]
Structs
A counter per key
A drop-in replacement for BTreeMap
, where the keys have the property of being array indices.
Some values may be missing. Much more efficient at operations on individual objects, because
it just becomes a simple array lookup.
Convenience functions around a string->string map
Use when your key is just PartialEq, not Ord or Hash.
Traits
Use with FixedMap
. From a particular key, extract a usize
. These values should be
roughly contiguous; the space used by the FixedMap
will be O(n)
with respect to the largest
value returned here.
