Function expectUnsigned

expectUnsigned(cbor: Cbor, options?: ExpectUnsignedOptions): number | bigint
Extract unsigned integer value, throwing if type doesn't match.

With options, the value is checked against a fixed width and, when wrapNegative is set, a negative node is wrapped exactly as the reference's u*::try_from wraps it (see ExpectUnsignedOptions).
Parameters
- cbor: Cbor
  CBOR value
- Optionaloptions: ExpectUnsignedOptions
  Fixed-width extraction (optional; without it the behaviour is the plain Unsigned-or-WrongType check)
Returns number | bigint
Unsigned integer (bigint above Number.MAX_SAFE_INTEGER)

Throws
WrongType if cbor is not an unsigned integer (or, with wrapNegative, not an integer); OutOfRange when the value does not fit width
