keys-2

Use keys-2 as a keyset predicate function to determine if there are at least two keys that match the keys defined in a keyset.

Basic syntax

To check whether there are at least two keys that match the keys defined in a keyset, use the following syntax:

keys-2 count matched

Note: keys-2 is intendeed to be used in keyset definitions, and not used directly in Pact code.

Arguments

Use the following arguments to specify the count of keys in the keyset and the number of matched keys using the keys-2 Pact function.

Argument	Type	Description
count	integer	Specifies the total count of keys defined in the keyset.
matched	integer	Specifies the number of matched keys.

Return value

The keys-2 function returns a boolean value indicating whether there are at least two keys that match the keys defined in the keyset.

Examples

The following example demonstrates how to use the keys-2 to check if at least two keys are matched in a keyset where the total number of keys defined in a keyset is three and only one key is matched:

pact> (keys-2 3 1)
false

The function returns false because the condition of having at least two keys matched is not met.
