Enum InitializeDecision 

pub enum InitializeDecision {
    Allow,
    PopulateSamplingSteward,
    RejectMissingSamplingCapability,
}

v0.9.0 P2: outcome of inspecting the tenant’s [llm] config + the peer’s sampling capability at MCP initialize time.

Separating the decision from the actual slot write makes the gating logic unit-testable without needing a real rmcp::Peer<RoleServer> (whose constructors are private). SoloMcpServer::initialize performs the match and routes to the side-effect path; tests pin the table directly.

Variants

Allow

Tenant’s LLM backend doesn’t require an MCP peer; the slot was populated eagerly at registry-open time (or stays None for LlmConfig::None). MCP initialize succeeds without writing the slot.

PopulateSamplingSteward

Tenant’s LLM backend is mcp_sampling AND the peer advertised the sampling capability. populate_sampling_steward writes a peer-bound Steward into the slot.

RejectMissingSamplingCapability

Tenant’s LLM backend is mcp_sampling but the peer did NOT advertise the sampling capability. MCP initialize must refuse with the locked BLOCKER 2 error message.

Trait Implementations

impl Clone for InitializeDecision

fn clone(&self) -> InitializeDecision

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InitializeDecision

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

Formats the value using the given formatter.

impl PartialEq for InitializeDecision

fn eq(&self, other: &InitializeDecision) -> 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.
