pub fn get_channel(endpoint: &str) -> Result<Channel, Error>Expand description
Return a [Channel] for endpoint, reusing a cached one if it exists.
The channel is connected lazily: no network activity occurs until the first RPC is made. Keepalive settings are applied at creation time from the environment variables documented in the module-level doc.
§Errors
Returns [tonic::transport::Error] if endpoint is not a valid URI.
§Panics
Panics if called outside a Tokio runtime context (required by tonic’s transport layer).
