Enum TransportCode 

pub enum TransportCode {
    NotFound,
    AlreadyExists,
    InvalidArgument,
    FailedPrecondition,
    Aborted,
    OutOfRange,
    ResourceExhausted,
    Unimplemented,
    DataLoss,
    Ambiguous,
    Unauthenticated,
    PermissionDenied,
    Unavailable,
    DeadlineExceeded,
    Internal,
}

Stable transport classification used by retry and fencing logic.

Variants

NotFound

Object was not found.

AlreadyExists

Conditional create found an existing object.

InvalidArgument

The request itself was invalid for the provider API surface.

FailedPrecondition

A precondition failed; on append/open this is a terminal writer fence, including both takeover revocation and finalized-object rejection.

Aborted

GCS redirected or aborted an operation. Rich zonal write redirects are consumed by the gRPC transport before reaching protocol code.

OutOfRange

Requested offset lies outside the provider’s accepted range.

ResourceExhausted

GCS throttled the request with HTTP 429 / RESOURCE_EXHAUSTED because a per-object mutation-rate or per-project quota was exhausted. The request remains valid and retry-with-backoff can succeed once quota state resets; this is not a permanent rejection.

Unimplemented

The provider does not implement the required operation.

DataLoss

Stored bytes or checksums are corrupt.

Ambiguous

The provider response cannot distinguish absence from a selector or routing failure. Recovery must fail closed rather than retrying away or interpreting this observation as a missing object.

Unauthenticated

No valid credential was supplied.

PermissionDenied

The credential lacks bucket permission.

Unavailable

Temporary service or zone outage.

DeadlineExceeded

Operation exceeded its deadline.

Internal

Unclassified internal transport failure.

Implementations

impl TransportCode

pub fn transient(self) -> bool

Whether retrying the same operation can be safe.

pub fn fences_writer(self) -> bool

Whether an append path must stop the current writer incarnation.

Trait Implementations

impl Clone for TransportCode

fn clone(&self) -> TransportCode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for TransportCode

impl Debug for TransportCode

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TransportCode

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for TransportCode

impl PartialEq for TransportCode

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

impl Serialize for TransportCode

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
