dig_rpc_types/
types.rs

1//! Request/response wire types for every DIG-node RPC method.
2//!
3//! Each type is `serde`-derived and models a method's params or result
4//! field-for-field with the canonical implementation (the digstore `dig-node`
5//! crate). Fields that appear only in one profile or only on the first window of
6//! a paged stream are `Option` and doc-flagged.
7//!
8//! Hex-encoded identifiers (`store_id`, `root`, `retrieval_key`, `peer_id`) are
9//! carried as `String` on the wire — lower-case 64-hex — because the interface
10//! crate does no crypto and imposes no byte-array dependency. Callers validate
11//! length/charset at their boundary.
12//!
13//! # Two content profiles, one chunk type
14//!
15//! [`ContentChunk`] models both the node profile (`dig.getContent` on the local
16//! dig-node) and the network profile (`rpc.dig.net`). The network-profile-only
17//! fields — [`total_length`](ContentChunk::total_length),
18//! [`length`](ContentChunk::length), [`program_hash`](ContentChunk::program_hash),
19//! [`offset`](ContentChunk::offset) — are `Option` so one type serves both
20//! surfaces with no silent split.
