srt_dart 1.0.0

Bindings of Secure Reliable Transport (SRT) protocol for Dart.

1.0.0

• Initial version.

Foundation (Lifecycle & Core Wrappers)

• Expose srtStartup() and srtCleanup() in a dart frindely class - Srt
  • Constructor SrtSocket, that calls srt_create_socket()
  • bind → wraps srt_bind()
  • listen → wraps srt_listen()
  • accept → wraps srt_accept()
  • connect → wraps srt_connect()
  • dispose → wraps srt_close()
  • state → wraps srt_getsockstate() (returns enum: OPENED, LISTENING, CONNECTING, CONNECTED, CLOSING, CLOSED)
• Create Error handling:
  • checkSrtResult show socket propietes when passed a non-expected value
  • SrtException throw a srt_getlasterror_str()
• Implement type-safe option builders:
  • SocketOptions class integrated with srt_setsockopt() with setters for common options (MSS, encryption, buffers, etc.)

Data Transfer - Stream, Message & File Transfer Modes

• Extend srt_socket.dart with:
  • sendStream → wraps srt_send()
  • recvStream → wraps srt_recv/srt_sendmsg2()
  • sendMessage → wraps srt_sendmsg2() with SRT_MSGCTRL in a dart frindely class
    • MessageControl wrapper for SRT_MSGCTRL with builder pattern
  • recvMessage → wraps srt_recvmsg2() and return a dart friendly class
    • SrtMessage class (payload, timestamp, sequence, etc.)
  • sendFile → wraps srt_sendfile()
  • recvFile → wraps srt_recvfile()
  • getStats → wraps srt_bstats() with SocketStats return type
  • getLocalAddress → wraps srt_getsockname() with address/port parsing
  • getRemoteAddress → wraps srt_getpeername() with address/port parsing
  • SocketStats class with comprehensive statistics fields

Epoll + Sugar on Top

• SrtEpoll class wrapping epoll functionality

  • register → wraps srt_epoll_add_usock() with EpollEventType enum
  • unregister → wraps srt_epoll_remove_usock()
  • waitAsync → wraps srt_epoll_wait() (returns list of ready events: READ, WRITE, ERROR)
  • clear → wraps srt_epoll_clear_usocks()
  • dispose → wraps srt_epoll_release()
  • waitAsStream → Continuous event stream

• Extend SrtSocket with:

  • waitStream - Continuous data of recvStream.
  • waitMessage - Continuous data of recvMenssage.
  • accept in a theared for async performece
  • sendStrem with a chunked mode for large data.

• Comprehensive unit tests for stream and message modes, and a documentation.
