Enum Error 

pub enum Error {
    Connect(Error),
    Rpc(Status),
}

Errors that can occur while talking to an opcda-bridge gateway.

Both variants use #[error(transparent)]: Display and source() forward straight through to the wrapped tonic error with no added prefix or extra chain link. This matters because opcda-bridge-client’s CLI commands convert this type into an anyhow::Error with a bare ? (the same way they converted a raw tonic::Status/ tonic::transport::Error before this crate existed); transparency keeps that conversion rendering byte-for-byte the same error text the CLI printed before this crate existed, which is part of this crate’s contract with its CLI consumer and is pinned down by test_error_rpc_anyhow_debug_matches_bare_status and client::tests::test_connect_failure_anyhow_debug_matches_bare_transport_error.

A dedicated thiserror enum (rather than reusing anyhow::Error here the way opcda-bridge-client’s own commands do) still lets a downstream consumer that does not want an anyhow dependency match on Error::Connect / Error::Rpc directly.

Variants

Connect(Error)

Failed to establish the gRPC channel to the gateway (e.g. connection refused, DNS failure, invalid address).

Rpc(Status)

The gateway returned a gRPC error for a ListServers/Browse/ Read/Write call, or for a Browse response-stream item.

Trait Implementations

impl Debug for Error

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Error

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for Error

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

Provides type-based access to context intended for error reports.

impl From<Error> for Error

fn from(source: Error) -> Self
