Struct Options 

#[non_exhaustive]
pub struct Options {
    pub strict_utf8_mapping: bool,
    pub generate_json: bool,
    pub extern_paths: Vec<(String, String)>,
    pub emit_register_fn: bool,
}

Options for ConnectRPC code generation.

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

Construct via Options { field: value, ..Options::default() }.

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.

strict_utf8_mapping: bool

Emit Vec<u8>/&[u8] for proto string fields with utf8_validation = NONE instead of String/&str. See buffa_codegen::CodeGenConfig::strict_utf8_mapping.

generate_json: bool

Emit serde::Serialize / serde::Deserialize derives and the proto3 JSON mapping helpers on generated message types. Required for the Connect protocol’s JSON codec; disable only if you’re targeting binary-only clients.

extern_paths: Vec<(String, String)>

Map protobuf package prefixes to Rust module paths for message types.

Each entry is (proto_prefix, rust_path), e.g. (".", "crate::proto") routes every type through crate::proto::.... More-specific prefixes win via longest-prefix-match, and the WKT mapping (.google.protobuf -> ::buffa_types::...) is auto-injected.

Used by generate_services to bake absolute paths into service stubs so they compile independently of co-generated message types. Unused by generate_files (the unified super::-relative path).

emit_register_fn: bool

Emit the per-file register_types(&mut TypeRegistry) function that aggregates every message in the file. Default true. See buffa_codegen::CodeGenConfig::emit_register_fn.

Set to false when multiple generated files are include!d into the same module — the identically-named register_types fns would otherwise collide. The per-message __*_JSON_ANY consts are still emitted; only the aggregating function is suppressed.

Trait Implementations

impl Default for Options

fn default() -> Self

Returns the “default value” for a type.
