Enum mz_persist::location::ExternalError

pub enum ExternalError {
    Determinate(Determinate),
    Indeterminate(Indeterminate),
}

An error coming from an underlying durability system (e.g. s3) or from invalid data received from one.

Variants

Determinate(Determinate)

A determinate error from an external system.

Indeterminate(Indeterminate)

An indeterminate error from an external system.

Implementations

impl ExternalError

pub fn new_timeout(deadline: Instant) -> Self

Returns a new error representing a timeout.

TODO: When we overhaul errors, this presumably should instead be a type that can be matched on.

pub fn is_timeout(&self) -> bool

Returns whether this error represents a timeout.

TODO: When we overhaul errors, this presumably should instead be a type that can be matched on.

Trait Implementations

impl Debug for ExternalError

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

Formats the value using the given formatter.

impl Display for ExternalError

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

Formats the value using the given formatter.

impl Error for ExternalError

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 PartialEq for ExternalError

An impl of PartialEq purely for convenience in tests and debug assertions.

fn eq(&self, other: &Self) -> 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.
