@psalm-assert-if-true

The @psalm-assert-if-true tag asserts the given type for an argument or variable when the function returns true. It is defined by the static analyzer Psalm, alongside @psalm-assert.

Parsing a @psalm-assert-if-true tag produces an AssertIfTrueTag instance, carrying the asserted $type and $variable alongside the $name and optional $description every Tag already provides.

The same AssertIfTrueTag is produced by @phpstan-assert-if-true and @phan-assert-if-true, which restate the same assertion for their respective tools.

See Psalm's supported annotations.
