Enum ReflectMode 

#[non_exhaustive]
pub enum ReflectMode {
    Off,
    Bridge,
    VTable,
}

How much reflection support generated types get.

Selected through buffa_build’s reflect_mode builder method (or the protoc-gen-buffa reflect_mode= option). All modes need the consuming crate to depend on buffa-descriptor with its reflect feature and on std; the call site is foo.reflect().get(fd) regardless of mode.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Off

No reflection impls.

Bridge

Reflectable::reflect() round-trips the message through a DynamicMessage (encode → decode → boxed handle). Smaller generated code; pays an allocation and a re-encode per reflect() call.

VTable

impl ReflectMessage directly on the owned and view types, and Reflectable::reflect() borrows self with no round-trip. Larger generated code; near-free reflective access. Does not require view generation — with views off, only the owned impls are emitted.

Implementations

impl ReflectMode

pub fn apply(self, config: &mut CodeGenConfig)

Apply this mode to a CodeGenConfig (sets generate_reflection / generate_reflection_vtable). Used by the buffa-build and protoc-gen-buffa front-ends.

Trait Implementations

impl Clone for ReflectMode

fn clone(&self) -> ReflectMode

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for ReflectMode

impl Debug for ReflectMode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ReflectMode

fn default() -> ReflectMode

Returns the “default value” for a type.

impl Eq for ReflectMode

impl PartialEq for ReflectMode

fn eq(&self, other: &ReflectMode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
