trulens.core.utils.containers ¶

Container class utilities.

Bases: set, Generic[T]

A set with max size that has blocking peek/get/add .

empty() -> bool

Check if the set is empty.

peek() -> T

Get an item from the set.

Blocks until an item is available.

remove(item: T)

Remove an item from the set.

pop() -> T

Get and remove an item from the set.

Blocks until an item is available.

add(item: T)

Add an item to the set.

Blocks if set is full.

first(seq: Sequence[T]) -> T

Get the first item in a sequence.

second(seq: Sequence[T]) -> T

Get the second item in a sequence.

third(seq: Sequence[T]) -> T

Get the third item in a sequence.

is_empty(obj)

Check if an object is empty.

If object is not a sequence, returns False.

dict_set_with(
    dict1: Dict[A, B], dict2: Dict[A, B]
) -> Dict[A, B]

Add the key/values from dict2 to dict1.

Mutates and returns dict1.

dict_set_with_multikey(
    dict1: Dict[A, B],
    dict2: Dict[Union[A, Tuple[A, ...]], B],
) -> Dict[A, B]

Like dict_set_with except the second dict can have tuples as keys in which case all of the listed keys are set to the given value.

dict_merge_with(
    dict1: Dict, dict2: Dict, merge: Callable
) -> Dict

Merge values from the second dictionary into the first.

If both dicts contain the same key, the given merge function is used to merge the values.
