Expand description

The configuration for WebSocket connection.

Fields

max_send_queue: Option<usize>

The size of the send queue. You can use it to turn on/off the backpressure features. None means here that the size of the queue is unlimited. The default value is the unlimited queue.

max_message_size: Option<usize>

The maximum size of a message. None means no size limit. The default value is 64 MiB which should be reasonably big for all normal use-cases but small enough to prevent memory eating by a malicious user.

max_frame_size: Option<usize>

The maximum size of a single message frame. None means no size limit. The limit is for frame payload NOT including the frame header. The default value is 16 MiB which should be reasonably big for all normal use-cases but small enough to prevent memory eating by a malicious user.

accept_unmasked_frames: bool

When set to true, the server will accept and handle unmasked frames from the client. According to the RFC 6455, the server must close the connection to the client in such cases, however it seems like there are some popular libraries that are sending unmasked frames, ignoring the RFC. By default this option is set to false, i.e. according to RFC 6455.
