keys-any

Use keys-any as a keyset predicate function to determine if at least one of the keys defined in the keyset is matched.

Basic syntax

To check whether one of the keys defined in a keyset is matched, use the following syntax:

(keys-any count matched)

Note: keys-any 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-any 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-any function returns a boolean value indicating whether one of the key in the keyset is matched.

Examples

The following example demonstrates how to use the keys-any function to check whether one of the keys is matched in a keyset where the total number of keys defined is three:

pact> (keys-any 1 3)
true

The function returns true because one key in the keyset is matched.
