Name of the disposed class, used in the message and exposed as DisposedError.className.
ReadonlyclassName of the disposed class, e.g. 'Identity', 'Handle', 'SubHandle'.
ReadonlycodeStable machine-readable failure code — match on this, not on messages.
ReadonlylevelLayer that produced the failure (see AttestationLevel).
StaticstackThe Error.stackTraceLimit property specifies the number of stack frames
collected by a stack trace (whether generated by new Error().stack or
Error.captureStackTrace(obj)).
The default value is 10 but may be set to any valid JavaScript number. Changes
will affect any stack trace captured after the value has been changed.
If set to a non-number value, or set to a negative number, stack traces will not capture any frames.
OptionalcauseOptionalstackStaticcaptureCreates a .stack property on targetObject, which when accessed returns
a string representing the location in the code at which
Error.captureStackTrace() was called.
const myObject = {};
Error.captureStackTrace(myObject);
myObject.stack; // Similar to `new Error().stack`
The first line of the trace will be prefixed with
${myObject.name}: ${myObject.message}.
The optional constructorOpt argument accepts a function. If given, all frames
above constructorOpt, including constructorOpt, will be omitted from the
generated stack trace.
The constructorOpt argument is useful for hiding implementation
details of error generation from the user. For instance:
function a() {
b();
}
function b() {
c();
}
function c() {
// Create an error without stack trace to avoid calculating the stack trace twice.
const { stackTraceLimit } = Error;
Error.stackTraceLimit = 0;
const error = new Error();
Error.stackTraceLimit = stackTraceLimit;
// Capture the stack trace above function b
Error.captureStackTrace(error, b); // Neither function c, nor b is included in the stack trace
throw error;
}
a();

Thrown when a method that requires key material is called on an Identity or a Handle/SubHandle that has been disposed via Identity.dispose / Handle.dispose.
The private key bytes are zeroized by
dispose(); calling a capability method afterwards is always a programming error, never a recoverable state — match one.name === 'DisposedError'(orinstanceof). As an AttestationError subclass it carriescode === 'DISPOSED'andlevel === 'FORMAT'.
