Enum DialError 

pub enum DialError {
    InvalidAddress {
        addr: String,
        source: InvalidUri,
    },
    Tls(String),
    Connect(ConnectError),
}

Errors an agent dial can produce.

Variants

InvalidAddress

Could not parse the configured agent address as a URI.

Fields

addr: String

The address string that failed to parse.

source: InvalidUri

The underlying URI parse error.

Tls(String)

Building the TLS client for an https:// endpoint failed (e.g. no process-default crypto provider). The dial fails closed rather than silently downgrading to plaintext.

Connect(ConnectError)

Connect-level error from the AgentService stream.

Implementations

impl DialError

pub const fn code(&self) -> Option<ErrorCode>

The Connect error code, when this is a transport-level Connect error (None for local address/TLS-setup failures).

pub const fn is_retryable(&self) -> bool

Whether retrying the call could plausibly succeed. Only transient transport conditions are retryable; terminal codes (InvalidArgument, Unauthenticated, NotFound, …) and local address/TLS failures are not. Edges use this to decide whether to ask the source platform to redeliver (retryable) or to drop / 4xx (terminal — redelivery would loop forever).

Trait Implementations

impl Debug for DialError

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

Formats the value using the given formatter.

impl Display for DialError

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

Formats the value using the given formatter.

impl Error for DialError

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

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

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

impl From<ConnectError> for DialError

fn from(source: ConnectError) -> Self

Converts to this type from the input type.
