Fields (Non-exhaustive)§
This struct is marked as non-exhaustive
Struct { .. }
syntax; cannot be matched against without a wildcard ..
; and struct update syntax will not work.read_buffer_size: usize
Read buffer capacity. This buffer is eagerly allocated and used for receiving messages.
For high read load scenarios a larger buffer, e.g. 128 KiB, improves performance.
For scenarios where you expect a lot of connections and don’t need high read load performance a smaller buffer, e.g. 4 KiB, would be appropriate to lower total memory usage.
The default value is 128 KiB.
write_buffer_size: usize
The target minimum size of the write buffer to reach before writing the data to the underlying stream. The default value is 128 KiB.
If set to 0
each message will be eagerly written to the underlying stream.
It is often more optimal to allow them to buffer a little, hence the default value.
Note: flush
will always fully write the buffer regardless.
max_write_buffer_size: usize
The max size of the write buffer in bytes. Setting this can provide backpressure in the case the write buffer is filling up due to write errors. The default value is unlimited.
Note: The write buffer only builds up past write_buffer_size
when writes to the underlying stream are failing. So the write buffer can not
fill up if you are not observing write errors even if not flushing.
Note: Should always be at least write_buffer_size + 1 message
and probably a little more depending on error handling strategy.
max_message_size: Option<usize>
The maximum size of an incoming 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 incoming 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.
per_message_deflate: Option<PerMessageDeflateConfig>
Per-message-deflate configuration, specify it
to enable per-message (de)compression using the Deflate algorithm
as specified by RFC7692
.
