Struct AcceptOptions 

pub struct AcceptOptions {
    pub allow_implicit_codec: bool,
    pub allowed_origins: Option<Vec<String>>,
}

Options controlling how the handshake picks a subprotocol to echo when the handler’s selector declines (see accept_with_options).

Fields

allow_implicit_codec: bool

When the selector returns None and the client did not offer DEFAULT_SUBPROTOCOL (h2ts), accept the client’s first offered subprotocol (or, if it offered none, complete with no subprotocol) instead of rejecting the handshake.

Off by default: a client that speaks neither h2ts nor a handler-selected protocol is rejected with WebSocketError::UnsupportedSubprotocol. Turn this on for a codec-agnostic tunnel that accepts whatever framing the client offered (e.g. a raw/binary tunnel, or a websockify-style binary client).

allowed_origins: Option<Vec<String>>

Opt-in Origin allowlist (Cross-Site WebSocket Hijacking defence). When Some, only handshakes whose Origin header matches one of these entries (ASCII case-insensitive, e.g. https://app.example.com) are accepted; everything else — including a missing Origin — is rejected with a 403 (WebSocketError::ForbiddenOrigin).

None (the default) accepts any origin. This mirrors nginx, which does no Origin validation by default and leaves it as an opt-in allowlist; a browser always sends Origin, so a legitimate browser client is unaffected.
