Data.Containers

Check if there is a value with the supplied key in the container.

Check if there isn't a value with the supplied key in the container.

Get the union of two containers.

Combine a collection of SetContainers, with left-most values overriding when there are matching keys.

Get the difference of two containers.

Get the intersection of two containers.

Get a list of all of the keys in the container.

Get the difference between two maps, using the left map's values.

Get the intersection of two maps, using the left map's values.

Get the intersection of two maps with a supplied function that takes in the left map's value and the right map's value.

Look up a value in a map with a specified key.

Insert a key-value pair into a map.

Delete a key-value pair of a map using a specified key.

Create a map from a single key-value pair.

Convert a list of key-value pairs to a map

Convert a map to a list of key-value pairs.

Like lookup, but uses a default value when the key does not exist in the map.

Insert a key-value pair into a map.

Inserts the value directly if the key does not exist in the map. Otherwise, apply a supplied function that accepts the new value and the previous value and insert that result into the map.

Insert a key-value pair into a map.

Inserts the value directly if the key does not exist in the map. Otherwise, apply a supplied function that accepts the key, the new value, and the previous value and insert that result into the map.

Insert a key-value pair into a map, return the previous key's value if it existed.

Inserts the value directly if the key does not exist in the map. Otherwise, apply a supplied function that accepts the key, the new value, and the previous value and insert that result into the map.

Apply a function to the value of a given key.

Returns the input map when the key-value pair does not exist.

Equivalent to adjustMap, but the function accepts the key, as well as the previous value.

Apply a function to the value of a given key.

If the function returns Nothing, this deletes the key-value pair.

Returns the input map when the key-value pair does not exist.

Equivalent to updateMap, but the function accepts the key, as well as the previous value.

Apply a function to the value of a given key.

If the map does not contain the key this returns Nothing and the input map.

If the map does contain the key but the function returns Nothing, this returns the previous value and the map with the key-value pair removed.

If the map contains the key and the function returns a value, this returns the new value and the map with the key-value pair with the new value.

Update/Delete the value of a given key.

Applies a function to previous value of a given key, if it results in Nothing delete the key-value pair from the map, otherwise replace the previous value with the new value.

Combine two maps.

When a key exists in both maps, apply a function to both of the values and use the result of that as the value of the key in the resulting map.

Combine a list of maps.

When a key exists in two different maps, apply a function to both of the values and use the result of that as the value of the key in the resulting map.

Apply a function over every key-value pair of a map.

Apply a function over every key of a pair and run unionsWith over the results.

Filter values in a map.

Equivalent to filterMap, but the function accepts the key, as well as the value.

Insert a value into a set.

Delete a value from a set.

Create a set from a single element.

Convert a list to a set.

Convert a set to a list.

Filter values in a set.

Combine each element of two MonoZips using a supplied function.

Take two MonoZips and return a list of the pairs of their elements.

Take a list of pairs of elements and return a MonoZip of the first components and a MonoZip of the second components.

Convert a map into a set of its keys.
