Abstract Readonly schemaJSON schema against which to validate values. When a schema
provides an errorMessage string option, all errors occurring for that
schema (but not for nested schemas) collapse into a single error having
this message. The errorMessage option allows you to provide a custom
error message for a schema. For example, an errorMessage on a schema
for a property of an object replaces TypeBox's built-in error messages
for errors that occur on that property.
Validates a value against the schema, halting validation at the first
validation error with a ValidationException. Does not clean values of
unrecognized properties.
ValidationException when the value is invalid, reporting only
the first validation error in the details property. The errorMessage
parameter provides the exception's overall error message.

Optional overallError: stringOverall eror message to report in the exception.
The substring {error}, if present, will be replaced with a string
representation of the error. Defaults to "Invalid value".
Validates a value against the schema, halting validation at the first

removes unrecognized properties from the provided value.

Validates a value against the schema, halting validation at the first

returns a copy of the value with unrecognized properties removed, but
returns the original value if there are no unrecognized properties.

The provided value itself if the value is not an object or if the value is an object having no unrecognized properties. If the value is an object having at least one unrecognized property, returns a copy of the value with unrecognized properties removed.
Protected Abstract assertProtected cleanProtected cleanAbstract errorsValidates a value against the schema and returns an iteratable whose
iterator yields the validation errors. The iterator tests the value for the
next error on each call to next(), returning a ValueError for the error
until done. It does not evaluate errors in advance of their being
requested, allowing you to short-circuit validation by stopping iteration
early. For performance reasons, it is best to call test() before calling
this method. This method does not throw ValidationException and does not
clean values of unrecognized properties.
Value to validate against the schema.
An iteratable yielding all validation errors. Upon detecting one
or more errors for a particular schema (possibly a nested schema), if the
schema provides an errorMessage property, only a single error is
reported for the schema, and the message property of this error is set
to errorMessage's value. Also, the TypeBox error "Expected required
property" is dropped when at least one other error is reported for the
property. Consequently, only the Type.Any and Type.Unknown schemas can
yield "Expected required property" errors.
Validates a value against the schema and returns the first error,
returning null if there is no error. No validation is performed beyond
the first error, allowing you to protect the server from wasting time and
memory validating excessively long strings. It is equivalent to calling
next() exactly once on the iterator returned by errors(), serving
only as a convenience method. For performance reasons, it is best to call
test() before calling this method. This method does not throw
ValidationException and does not clean values of unrecognized properties.
Value to validate against the schema.
The first validation error, if there is a validation error,
otherwise null.
Abstract testTests whether a value conforms to the schema. For performance reasons, it
is best to call this method before calling errors() or firstError(),

throw ValidationException and does not clean values of unrecognized
properties.

Tests whether a value conforms to the schema, returning an iterable whose
iterator yields the validation errors, or returning null if there are no
validation errors. This method is equivalent to calling test() and then
errors() and exists only for convenience. The method does not throw
