Struct wasmtime_wasi::preview2::bindings::wasi::sockets::tcp::TcpSocket

pub struct TcpSocket { /* private fields */ }

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/TcpSocketOperationalSemantics.md for a 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.

The inner state is wrapped in an Arc because the same underlying socket is used for implementing the stream types.

Implementations
