Bertex

Elixir BERT encoder/decoder. See http://bert-rpc.org for full spec.

The following types can be automatically encoded and decoded.

integer   <-> BERT integer
float     <-> BERT float
atom      <-> BERT atom
tuple     <-> BERT tuple
list      <-> BERT list or BERT bytelist
binary    <-> BERT binary
[]        <-> BERT nil (complex)
bool      <-> BERT boolean (complex)
Map       <-> BERT dict (complex)

To encode Elixir terms to BERT binaries, use:

Bertex.encode(term) -> binary

To decode BERT binaries to Elixir terms, use:

Bertex.decode(binary) -> term

To safely decode BERT binaries to Elixir terms, use:

Bertex.safe_decode(binary) -> term
