Enumeration Type Documentation

udp_variant

enum class idfxx::net::netconn::udp_variant : int

strong

UDP transport variant for datagram netconn channels.

Most UDP traffic uses standard (with checksums). The lite and no_checksum variants are specialized — only set them if you know your peer expects the corresponding wire format.

Enumerator
standard	Standard UDP.
lite	UDP-Lite (RFC 3828).
no_checksum	UDP with checksums disabled.

write_flag

enum class idfxx::net::netconn::write_flag : uint8_t

strong

Flags accepted by stream_channel::send / try_send.

The default (no flags set) copies the data into the stack's buffers, so the caller may reuse or destroy its buffer as soon as the call returns. Set no_copy to reference the caller's buffer instead — see the lifetime warning on that flag.

Enumerator
no_copy	Zero-copy: reference the caller's buffer rather than copying it. Warning The referenced memory must remain valid not just until the call returns, but until the data has been transmitted and acknowledged by the peer — try_send returns once the data is enqueued, while the stack continues to hold the reference for retransmission. Use only for storage that outlives the connection (e.g. static or flash-resident data); never for stack or soon-freed buffers.
more	Suppress the TCP PSH flag (allow more data to be coalesced).
dont_block	Return immediately rather than waiting for buffer space.
