Variants (Non-exhaustive)§

This enum is marked as 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.
§

InvalidConfig

設定値が不正(固定文の理由)。

Fields

§reason: &'static str

固定文の理由。

§

WorldSizeOutOfRange

world_size が 1..=max の範囲外。

Fields

§world_size: usize

指定値。

§max: usize

上限。

§

RankOutOfRange

ランク番号が 0..world_size の範囲外。

Fields

§rank: usize

指定値。

§world_size: usize

world_size。

§

NonLoopbackNotAllowed

非 loopback のアドレスが opt-in 無しで指定された。

Fields

§addr: SocketAddr

該当アドレス。

§

DuplicateRank

同じランク番号が重複した。

Fields

§rank: usize

重複したランク。

§

WorldSizeMismatch

ピアの world_size が自分と違う。

Fields

§expected: usize

自分の world_size。

§got: usize

ピアの申告値。

§

UnexpectedRank

リングの相手が想定したランクと違う。

Fields

§expected: usize

想定したランク。

§got: usize

ピアの申告値。

§

Protocol

ワイヤ上のプロトコル違反(固定文と数値だけの説明。ピアのバイト列は含まない)。

Fields

§message: String

説明文。

§

Timeout

タイムアウト。

Fields

§phase: &'static str

固定文の段階名。

§

PeerDisconnected

ピアが切断した。

§

Io(Error)

その他の I/O エラー。

§

Poisoned

communicator が poisoned(以後の集合通信は拒否される。復旧は範囲外)。

§

Backend(BackendError)

勾配の読み出しや optimizer ステップが返したバックエンドエラー。

§

GradientLengthMismatch

平坦化した勾配の長さがストアの総要素数と一致しない。

Fields

§expected: usize

ストアの総要素数。

§got: usize

平坦化後の長さ。

§

Other

将来 autodiff 側に増える variant の受け皿(現行の全 variant はこれ以外へ写る)。

Fields

§message: String

説明文。
