Struct Adapter 

pub struct Adapter { /* private fields */ }

The solver process: one sampler kind, and a session per live solver_id.

Feed it decoded SolverMessages with handle; it returns the reply to send back (or None for a cast that expects none). The startup SolverSpecCast is produced by spec_message.

Implementations

impl Adapter

pub fn new(kind: SamplerKind) -> Self

A fresh adapter that will run kind for every session it is asked to create, assuming DEFAULT_BUDGET_TRIALS.

pub const fn with_budget(self, budget: Budget) -> Self

Declares the trial budget kurobako will actually run each study for.

Only SamplerKind::Auto reads it, and only when a session is created; live sessions keep the budget they were created with, so this is meaningless after the first CREATE_SOLVER_CAST and is therefore a construction-time builder step rather than a setter.

pub fn spec_message(&self) -> SolverMessage

The startup message announcing this solver to kurobako.

pub fn handle(&mut self, message: SolverMessage) -> Option<SolverMessage>

Handles one inbound message, returning the reply to send (if any).

Casts (CreateSolverCast, DropSolverCast) return None; calls (AskCall, TellCall) return their reply or an ErrorReply. A message a solver should never receive is logged to stderr and ignored, which is the safe choice against a desynchronized stream.

Trait Implementations

impl Debug for Adapter

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

Formats the value using the given formatter.
