Crate wasmcloud_actor_telnet[−][src]
Telnet Server wasmCloud Actor Interface
This crate provides an abstraction over the wasmcloud:telnet
contract. This allows
actors to be notified when a new telnet session has started and when text has been
received on a given session. Actors can also emit text to a specific session, which
ultimately correlates to an individual connected socket client.
Example:
extern crate wasmcloud_actor_telnet as telnet; extern crate wasmcloud_actor_core as actorcore; use telnet::TelnetResult; use wapc_guest::HandlerResult; #[actorcore::init] pub fn init() { telnet::Handlers::register_session_started(session_started); telnet::Handlers::register_receive_text(receive_text); } fn session_started(session: String) -> HandlerResult<TelnetResult> { let _ = telnet::default().send_text(session, "Welcome to the Interwebs!\n".to_string()); Ok(TelnetResult { success: true, error: None, }) } fn receive_text(session: String, text: String) -> HandlerResult<TelnetResult> { let _ = telnet::default().send_text(session, format!("Echo: {}\n", text)); Ok(TelnetResult { success: true, error: None, }) }

Functions
default | Creates the default host binding for the telnet capability |
deserialize | The standard function for de-serializing codec structs from a format suitable for message exchange between actor and host. Use of any other function to deserialize could result in breaking incompatibilities. |
host | Creates a named host binding for the telnet capability |
serialize | The standard function for serializing codec structs into a format that can be used for message exchange between actor and host. Use of any other function to serialize could result in breaking incompatibilities. |
