pub struct TcpSocket { /* private fields */ }
Expand description
A TCP socket resource.
The socket can be in one of the following states:
unbound
bind-in-progress
bound
(See note below)listen-in-progress
listening
connect-in-progress
connected
closed
See https://github.com/WebAssembly/wasi-sockets/blob/main/TcpSocketOperationalSemantics.md for more information.
Note: Except where explicitly mentioned, whenever this documentation uses
the term “bound” without backticks it actually means: in the bound
state or higher.
(i.e. bound
, listen-in-progress
, listening
, connect-in-progress
or connected
)
In addition to the general error codes documented on the
network::error-code
type, TCP socket methods may always return
error(invalid-state)
when in the closed
state.
A host TCP socket, plus associated bookkeeping.
