Struct Options 

#[non_exhaustive]
pub struct Options {
    pub buffa: CodeGenConfig,
    pub gate_client_feature: bool,
}

Options for ConnectRPC code generation.

These control both the underlying buffa message generation and the ConnectRPC service binding generation.

Construct via Options::default() then set fields on buffa directly (the struct is #[non_exhaustive], so struct-update syntax is unavailable from outside this crate).

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

buffa: CodeGenConfig

The underlying buffa-codegen configuration. Set any CodeGenConfig field directly here; connectrpc passes it through verbatim except for CodeGenConfig::generate_views, which is forced to true (service stubs require view types).

Options::default() starts from buffa’s defaults but enables generate_json (the Connect protocol’s JSON codec needs it; buffa’s own default is false).

buffa.extern_paths is used by generate_services to bake absolute paths into service stubs (set a (".", "crate::proto") catch-all so every type resolves); it is ignored by generate_files (the unified super::-relative path).

Every extern_path target must be buffa-generated code from buffa ≥ 0.7.0 with views enabled (and, if the crate feature-gates its generated impls, with that feature turned on): the service stubs rely on the buffa::HasMessageView impls and FooOwnedView wrappers emitted alongside each message, the same way they rely on the JSON/Serialize impls. buffa-types 0.7+ satisfies this for the well-known types. A crate generated without them fails to compile against the stubs (missing HasMessageView impl).

gate_client_feature: bool

When true, prefix every emitted FooClient<T> struct and its impl block with #[cfg(feature = "client")]. Opt in when the consuming crate wants to give server-only deployments a way to drop the client transport stack from their dependency graph.
