remoteMaxStreamsBidirectional

TypeScript

get remoteMaxStreamsBidirectional(): number

Swift declaration

var remoteMaxStreamsBidirectional: Int { get }

Get the maximum number of bidirectional streams advertised by peer that an application is allowed to create. Note that while attempts to create streams above this limit will be blocked until the server increases the limit, these blocked attempts will cause a STREAMS_BLOCKED frame to be sent to the server. This informs the server that the client has more streams it would like to create. As a result, the caller should attempt to create streams over this limit if it desires more streams.
