cinchcli-core 0.1.1

//! REST DTOs for the relay's legacy HTTP+JSON endpoints.
//!
//! Wire types are generated from `proto/cinch/v1/*.proto` at build time
//! (see `build.rs`); this module re-exports them under the names the CLI
//! and desktop already use. The generated types preserve snake_case JSON +
//! Go-style `omitempty` semantics via per-field `skip_serializing_if`
//! attribute injection.
//!
//! `ContentType` is a thin Rust-side enum kept for the CLI's auto-detection
//! pipeline. On the wire it round-trips through the proto's `string`
//! `content_type` field via `From<ContentType> for &'static str` so callers
//! can keep producing strongly typed values.
