decodeCborSequence

function

function decodeCborSequence(input: Uint8Array): CborType[]

Decodes a CBOR-sequence-encoded Uint8Array into the JavaScript equivalent values represented as a CBorType array. RFC 8949 - Concise Binary Object Representation (CBOR)

Limitations:

• While CBOR does support map keys of any type, this implementation only supports map keys being of type string, and will throw if detected decoding otherwise.
• This decoder will throw an error if duplicate keys are detected.

Notice: This decoder handles the tag numbers 0, and 1 automatically, all others returned are wrapped in a CborTag instance.

input: Uint8Array

The value to decode of type CBOR-sequence-encoded Uint8Array.

Returns

A CborType array representing the decoded data.
