class Connection -
module Continued -
class ContinuationFrameThe CONTINUATION frame is used to continue a sequence of header block fragments. Any number of CONTINUATION frames can be sent, as long as the preceding frame is on the same stream and is a HEADERS, PUSH_PROMISE, or CONTINUATION frame without the END_HEADERS flag set.
-
class DataFrameDATA frames convey arbitrary, variable-length sequences of octets associated with a stream. One or more DATA frames are used, for instance, to carry HTTP request or response payloads.
-
class Dependency -
class ErrorStatus codes as defined by https://tools.ietf.org/html/rfc7540#section-7.
-
class HandshakeErrorRaised if connection header is missing or invalid indicating that
-
class ProtocolErrorRaised by stream or connection handlers, results in GOAWAY frame
-
class StreamError -
class StreamClosed -
class GoawayError -
class FrameSizeErrorWhen the frame payload does not match expectations.
-
class HeaderError -
class FlowControlErrorRaised on invalid flow control frame or command.

module FlowControlled -
class Frame -
class Framer -
class GoawayFrameThe GOAWAY frame is used to initiate shutdown of a connection or to signal serious error conditions. GOAWAY allows an endpoint to gracefully stop accepting new streams while still finishing processing of previously established streams. This enables administrative actions, like server maintenance.
-
class HeadersFrameThe HEADERS frame is used to open a stream, and additionally carries a header block fragment. HEADERS frames can be sent on a stream in the "idle", "reserved (local)", "open", or "half-closed (remote)" state.
-
module PaddedCertain frames can have padding:
-
module Acknowledgement -
class PingFrameThe PING frame is a mechanism for measuring a minimal round-trip time from the sender, as well as determining whether an idle connection is still functional. PING frames can be sent from any endpoint.
-
class PriorityStream Dependency: A 31-bit stream identifier for the stream that
-
class PriorityFrameThe PRIORITY frame specifies the sender-advised priority of a stream. It can be sent in any stream state, including idle or closed streams.
-
class PushPromiseFrameThe PUSH_PROMISE frame is used to notify the peer endpoint in advance of streams the sender intends to initiate. The PUSH_PROMISE frame includes the unsigned 31-bit identifier of the stream the endpoint plans to create along with a set of headers that provide additional context for the stream.
-
class ResetStreamFrameThe RST_STREAM frame allows for immediate termination of a stream. RST_STREAM is sent to request cancellation of a stream or to indicate that an error condition has occurred.
-
class Server -
class Settings -
class PendingSettings -
class SettingsFrameThe SETTINGS frame conveys configuration parameters that affect how endpoints communicate, such as preferences and constraints on peer behavior. The SETTINGS frame is also used to acknowledge the receipt of those parameters. Individually, a SETTINGS parameter can also be referred to as a "setting".
-
class StreamA single HTTP/2 connection can multiplex multiple streams in parallel:
-
class Window -
class LocalWindowThis is a window which efficiently maintains a desired capacity.
-
class WindowUpdateFrameThe WINDOW_UPDATE frame is used to implement flow control.
