Functions

f assert	Asserts that the given value satisfies the provided predicate.
f ensure	Ensures that the given value satisfies the provided predicate.
f isAllOf	Return a type predicate function that returns `true` if the type of `x` is `AllOf<T>`.
f isAny	Always return `true` regardless of the type of `x`.
f isArray	Return `true` if the type of `x` is `unknown[]`.
f isArrayOf	Return a type predicate function that returns `true` if the type of `x` is `T[]`.
f isBigInt	Return `true` if the type of `x` is `bigint`.
f isBoolean	Return `true` if the type of `x` is `boolean`.
f isFunction	Return `true` if the type of `x` is `function`.
f isInstanceOf	Return `true` if the type of `x` is instance of `ctor`.
f isLiteralOf	Return a type predicate function that returns `true` if the type of `x` is a literal type of `pred`.
f isLiteralOneOf	Return a type predicate function that returns `true` if the type of `x` is one of literal type in `preds`.
f isNull	Return `true` if the type of `x` is `null`.
f isNullish	Return `true` if the type of `x` is `null` or `undefined`.
f isNumber	Return `true` if the type of `x` is `number`.
f isObjectOf	Return a type predicate function that returns `true` if the type of `x` is `ObjectOf<T>`. If `is.OptionalOf()` is specified in the predicate function, the property becomes optional. When `options.strict` is `true`, the number of keys of `x` must be equal to the number of keys of `predObj`. Otherwise, the number of keys of `x` must be greater than or equal to the number of keys of `predObj`.
f isOneOf	Return a type predicate function that returns `true` if the type of `x` is `OneOf<T>`.
f isOptionalOf	Return a type predicate function that returns `true` if the type of `x` is `T` or `undefined`.
f isPrimitive	Return `true` if the type of `x` is Primitive.
f isRecord	Return `true` if the type of `x` is `RecordOf<unknown>`.
f isRecordOf	Return a type predicate function that returns `true` if the type of `x` is `RecordOf<T>`.
f isString	Return `true` if the type of `x` is `string`.
f isSymbol	Return `true` if the type of `x` is `symbol`.
f isTupleOf	Return a type predicate function that returns `true` if the type of `x` is `TupleOf<T>`.
f isUndefined	Return `true` if the type of `x` is `undefined`.
f isUniformTupleOf	Return a type predicate function that returns `true` if the type of `x` is `UniformTupleOf<T>`.
f maybe	Returns the input value if it satisfies the provided predicate, or `undefined` otherwise.
f setAssertMessageFactory	Sets the factory function used to generate assertion error messages.
