}

An error that occurred while acquiring a resource.

Variants

AlreadyLeased

The resource is already leased by something else in this process.

Fields

kind: ResourceKind

Kind of the resource.

key: MetaString

Key of the resource.

owner: MetaString

Rendered identity of the subsystem holding the resource.

This is the authoritative answer to who holds the resource. Rendered rather than kept as a SubsystemIdentifier, which stores enough segments inline to make this error large enough to slow down every Result that carries it.

acquisition_process_id: Id

Identifier of the process that acquired the resource.

TypeMismatch

The key is registered, but holds a different type of resource.

Two specifications of the same kind produced the same key while naming different resource types, which means their keys are not as unique as they need to be.

Fields

kind: ResourceKind

Kind of the resource.

key: MetaString

Key of the resource.

existing_type: &'static str

Type the resource was registered as.

requested_type: &'static str

Type the resource was requested as.

CreationFailed

The resource could not be created.

Fields

kind: ResourceKind

Kind of the resource.

key: MetaString

Key of the resource.

source: GenericError

Source of the error.

Trait Implementations

impl Debug for AcquireError

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

Formats the value using the given formatter.

impl Display for AcquireError

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

Formats the value using the given formatter.

impl Error for AcquireError

where Self: Debug + Display,

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 ErrorCompat for AcquireError

fn backtrace(&self) -> Option<&Backtrace>

Returns a Backtrace that may be printed.

fn iter_chain(&self) -> ChainCompat<'_, '_>

where Self: AsErrorSource,

Returns an iterator for traversing the chain of errors, starting with the current error and continuing with recursive calls to Error::source.
