HashSet package:tomland

Codec for HashSet of values. Represented in TOML as an array of tables. Example: Haskell HashSet Int can look like this in your TOML file:

foo =
[ {a = 1}
, {a = 2}
]

Decodes to an empty HashSet in case of the missing field in TOML.

Takes a BiMap of a value and returns a BiMap for a HashSet of values and AnyValue as an array. Usually used as the arrayHashSetOf combinator.

Codec for hash sets. Takes converter for single hashable value and returns a set of hashable values. Example: Haskell HashSet Int can look like this in your TOML file:

foo = [1, 2, 3]

In case of the missing field, the following error will be seen:
