Funx.Predicate.IsFalse (funx v0.8.4)

Predicate that checks if a value is false.

This is a convenience predicate for checking boolean flags. Uses strict equality (== false), not falsiness.

Examples

use Funx.Predicate

# Check if a flag is false
pred do
  check [:bleeding, :staunched], IsFalse
end

# Equivalent to
pred do
  check [:bleeding, :staunched], fn staunched -> staunched == false end
end

# Also equivalent to
pred do
  negate check [:bleeding, :staunched], IsTrue
end
