Implementations

impl Error

pub fn generic(message: impl ToString) -> Self

impl Error

pub fn is_not_found(&self) -> bool

pub fn is_already_exists(&self) -> bool

pub fn is_permission_denied(&self) -> bool

pub fn is_unauthenticated(&self) -> bool

pub fn is_commit_conflict(&self) -> bool

Whether this is a Delta CommitVersionConflictException (409): a concurrent commit ratified the proposed version first. The caller should rebuild its snapshot and retry the commit.

pub fn is_update_requirement_conflict(&self) -> bool

Whether this is a Delta UpdateRequirementConflictException (409): an assert-etag/assert-table-uuid requirement was not met. The caller should reload the table and retry.

pub fn is_resource_exhausted(&self) -> bool

Whether this is a Delta ResourceExhaustedException / TooManyRequestsException (429): the request was throttled or hit the unbackfilled-commit limit. The caller should back off (and backfill pending commits) before retrying.

pub fn is_commit_state_unknown(&self) -> bool

Whether this is a Delta CommitStateUnknownException (500): the commit outcome is unknown. The caller must check table state before retrying to avoid duplicate commits.

pub fn is_unsupported_table_format(&self) -> bool

Whether this is a Delta UnsupportedTableFormatException (400): the table is not Delta, or is a Delta table this /delta/v1 endpoint does not support. The caller should fall back to the legacy UC table API.

pub fn is_not_implemented(&self) -> bool

Whether this is a Delta NotImplementedException (501): the server does not implement this /delta/v1 functionality. The caller should fall back to the legacy UC table API.

pub fn is_route_missing(&self) -> bool

Whether this is a 404 that is not a recognizable Delta error envelope — i.e. the /delta/v1 route itself is absent (no UnsupportedTableFormat / NoSuchTable envelope was returned), as on a UC deployment that does not serve /delta/v1 at all.

This is deliberately distinct from Error::is_not_found: an enveloped NoSuchTableException (a genuinely missing table) is an Error::Delta and returns false here, so callers can fall back on a missing route without masking a missing table.

pub fn should_fall_back_to_legacy(&self) -> bool

Whether the caller should react to this /delta/v1 loadTable error by falling back to the legacy UC table API (filesystem snapshot): an unsupported table format, an unimplemented endpoint, or an entirely missing route. A genuine NoSuchTable/auth/other error returns false and must be propagated.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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
