Struct MethodDescriptor 

#[non_exhaustive]
pub struct MethodDescriptor {
    pub kind: MethodKind,
    pub idempotent: bool,
    pub spec: Option<Spec>,
}

Description of a method returned by Dispatcher::lookup.

Carries only enough information to select the correct body-processing path in handle_request; the actual handler invocation happens in a separate call_* step.

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.

kind: MethodKind

The kind of RPC method.

idempotent: bool

Whether the method has no side effects and is eligible for Connect GET.

Only meaningful for MethodKind::Unary. Always false for streaming.

This is a narrower flag than Spec::idempotency_level: it is true only for IdempotencyLevel::NoSideEffects. Methods declared Idempotent (safe to retry but side-effecting) report idempotent == false here while carrying the full level in spec.

spec: Option<Spec>

Static method metadata, when known.

Code-generated dispatchers always supply a Spec; the dynamic Router returns None because its method paths are owned Strings and Spec::procedure requires &'static str.

Implementations

impl MethodDescriptor

pub const fn unary(idempotent: bool) -> Self

Convenience constructor for unary methods.

pub const fn server_streaming() -> Self

Convenience constructor for server-streaming methods.

pub const fn client_streaming() -> Self

Convenience constructor for client-streaming methods.

pub const fn bidi_streaming() -> Self

Convenience constructor for bidirectional streaming methods.

pub const fn from_kind(kind: MethodKind) -> Self

Construct a descriptor for the given MethodKind with default idempotent (false) and no Spec.

pub const fn with_idempotent(self, idempotent: bool) -> Self

Set the idempotency flag. Returns self for chaining.

pub const fn with_spec(self, spec: Spec) -> Self

Attach a Spec. Returns self for chaining.

Generated dispatchers call this so RequestContext::spec is populated for handlers and interceptors.
