jsondec

Minimal JSON parser. Converts JSON to R objects with proper type handling.

Fast and memory-efficient streaming hash functions,
binary/text encoding and serialization. Hashes strings and raw vectors
directly.  Stream hashes files which can be larger than memory, as
well as in-memory objects through R's serialization mechanism.
Implements the SHA-256, SHA-3 and 'Keccak' cryptographic hash
functions, SHAKE256 extendable-output function (XOF), 'SipHash'
pseudo-random function, base64 (including the URL-safe variant) and
base58 encoding, 'CBOR' and 'JSON' serialization.

jsondec function

<dl><dt>x</dt>
<dd>Character string or raw vector containing JSON data.</dd></dl>

Arguments

<ul>
<li>Object <code><a href="/link/%7B%7D?package=secretbase&version=1.3.0" data-mini-rdoc="secretbase::{}">{}</a></code> -&gt; named list</li>
<li>Array <code>[]</code> -&gt; unnamed list</li>
<li>String -&gt; character</li>
<li>Number -&gt; numeric</li>
<li><code>true</code>/<code>false</code> -&gt; logical</li>
<li><code>null</code> -&gt; <code>NULL</code></li>
</ul>

Type Mappings

<ul>
<li>Invalid JSON returns an empty list instead of erroring.</li>
<li>Duplicate keys are preserved; R accessors (<code>$</code>, <code>[[</code>) return first
match.</li>
<li>Non-standard number forms may be accepted (e.g., leading zeros,
hexadecimal).</li>
<li>Invalid escape sequences are output literally (e.g., <code>\\uZZZZ</code>
becomes <code>"uZZZZ"</code>).</li>
<li>Incomplete Unicode escape sequences for emoji are tolerated.</li>
<li>Nesting depth is limited to 512 levels.</li>
</ul>
