Enum SendUpdateError

#[non_exhaustive]
pub enum SendUpdateError {
    ConnectionClosed,
}

An error caused while trying to send an update to a method.

These errors should be impossible in our current implementation, since they can only happen if the mpsc::Receiver is closed—which can only happen when the session loop drops it, which only happens when the session loop has stopped polling its FuturesUnordered full of RPC request futures. Thus, any send that would encounter this error should be in a future that is never polled under circumstances when the error could happen.

Still, programming errors are real, so we are handling this rather than declaring it a panic or something.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

ConnectionClosed

The request was cancelled, or the connection was closed.

Trait Implementations
