Variants

Parse(String)

Semantic(String)

Storage(String)

FileDescriptors(FileDescriptorError)

StorageIntegrity(String)

ProjectionBusy

A registered Search target is retained by another native operation.

Execution(String)

ResourceBudgetExceeded(Box<ResourceBudgetError>)

Box the diagnostic so successful Result values do not grow with its fields.

ReadBudgetExceeded(ReadBudgetError)

GraphExpansionCandidateLimitExceeded

Fields

requested: usize

limit: usize

GraphExpansionPayloadLimitExceeded

Fields

requested: usize

limit: usize

TransactionConflict

Fields

read_epoch: u64

committed_epoch: u64

key: String

TransactionReadDependencyRefused

Requested read validation cannot be proved; never downgrade isolation.

Fields

reason: String

AppendSequenceExhausted

Fields

table: String

watermark: i64

requested: usize

CapabilityUnavailable

Fields

capability: RuntimeCapability

BranchCommandUnsupported

Fields

command: &'static str

context: &'static str

BranchBusy

Fields

resource: &'static str

BranchEvidenceBudgetExceeded

Fields

resource: &'static str

requested: u64

limit: u64

BranchReclamationBlocked

An unleased pending create prevents a complete reclamation mark. This identifies retained evidence, not authorization to discard it.

Fields

branch_id: Uuid

catalog_revision: u64

metadata_revision: u64

cause: Box<HawDBError>

Implementations

impl HawDBError

pub fn read_budget_exceeded( resource: ReadBudgetResource, limit: usize, message: impl Into<String>, ) -> Self

pub fn from_storage_error(error: impl Error + 'static) -> Self

Preserve a resource rejection through nested storage error wrappers.

pub fn from_storage_error_with_context( error: impl Error + 'static, context: &str, ) -> Self

from_storage_error, prefixing a generic Storage message with context and leaving a preserved typed cause (e.g. FileDescriptors) unprefixed and unchanged.

pub const fn is_retryable_transaction_conflict(&self) -> bool

Trait Implementations

impl Clone for HawDBError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HawDBError

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

Formats the value using the given formatter.

impl Display for HawDBError

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

Formats the value using the given formatter.

impl Eq for HawDBError

impl Error for HawDBError

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<Error> for HawDBError

fn from(error: Error) -> Self

Converts to this type from the input type.

impl From<ResourceBudgetError> for HawDBError

fn from(error: ResourceBudgetError) -> Self

Converts to this type from the input type.

impl PartialEq for HawDBError

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

Equality operator ==.

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

Inequality operator !=.
