Global Config And Liteserver Descriptors

TON global config JSON gives static entry points for clients. The crate currently parses liteserver entries.

Liteserver Descriptor

Fields:

• ip: signed 32-bit integer containing IPv4 bits,
• port: TCP port,
• id: public key object.

Public key form:

{
  "@type": "pub.ed25519",
  "key": "base64..."
}

IP Conversion

The signed integer should be reinterpreted as u32 bits, then converted to Ipv4Addr.

Edge cases:

• negative input,
• 0.0.0.0,
• 127.0.0.1,
• 255.255.255.255.

Feature Boundary

• JSON parsing: network-config.
• HTTP download: cli or future optional HTTP feature.

Library users should be able to provide config JSON without enabling HTTP.

Tests

Required tests:

• base64 public key decode,
• invalid key rejection,
• signed IP roundtrip,
• socket address creation,
• serialization roundtrip.
