Product-neutral fleet discovery, connection, command, and transfer failure.

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.

Topology(TopologyError)

Topology contract validation failed.

Request(RequestError)

Request contract validation failed.

TargetNotFound(HostId)

A requested host did not exist in the current snapshot.

StaleTopology

The caller bound work to an obsolete host revision.

Fields

host: HostId

Host whose topology changed.

expected: TopologyRevision

Revision bound by the request or cached connection.

actual: TopologyRevision

Current topology revision.

Cancelled

Cancellation was observed before completion.

DeadlineExceeded

The absolute or per-target deadline elapsed.

Connection

A connection driver failed.

Fields

host: HostId

Failed host.

message: String

Driver-safe diagnostic text.

Command

A command driver failed before returning a process result.

Fields

host: HostId

Failed host.

message: String

Driver-safe diagnostic text.

RemoteCommandDetached

A post-spawn remote command was detached and may still be running.

Fields

host: HostId

Remote target.

reason: &'static str

Cancellation or deadline reason.

Transfer

A file transfer driver failed.

Fields

source_host: HostId

Source host.

destination_host: HostId

Destination host.

message: String

Driver-safe diagnostic text.

TransferLifecycle(String)

Transfer lifecycle accounting was invalid.

EventSink(String)

Event emission failed after the underlying action.

Trait Implementations

impl Clone for FleetError

fn clone(&self) -> FleetError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FleetError

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

Formats the value using the given formatter.

impl Display for FleetError

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

Formats the value using the given formatter.

impl Error for FleetError

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<RequestError> for FleetError

fn from(source: RequestError) -> Self

Converts to this type from the input type.

impl From<TopologyError> for FleetError

fn from(source: TopologyError) -> Self

Converts to this type from the input type.

impl PartialEq for FleetError

fn eq(&self, other: &FleetError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
