Lance Namespace error codes.

These codes are globally unique across all Lance Namespace implementations (Python, Java, Rust, REST). Use these codes for programmatic error handling.

Variants

Unsupported = 0

Operation not supported by this backend

NamespaceNotFound = 1

The specified namespace does not exist

NamespaceAlreadyExists = 2

A namespace with this name already exists

NamespaceNotEmpty = 3

Namespace contains tables or child namespaces

TableNotFound = 4

The specified table does not exist

TableAlreadyExists = 5

A table with this name already exists

TableIndexNotFound = 6

The specified table index does not exist

TableIndexAlreadyExists = 7

A table index with this name already exists

TableTagNotFound = 8

The specified table tag does not exist

TableTagAlreadyExists = 9

A table tag with this name already exists

TransactionNotFound = 10

The specified transaction does not exist

TableVersionNotFound = 11

The specified table version does not exist

TableColumnNotFound = 12

The specified table column does not exist

InvalidInput = 13

Malformed request or invalid parameters

ConcurrentModification = 14

Optimistic concurrency conflict

PermissionDenied = 15

User lacks permission for this operation

Unauthenticated = 16

Authentication credentials are missing or invalid

ServiceUnavailable = 17

Service is temporarily unavailable

Internal = 18

Unexpected server/implementation error

InvalidTableState = 19

Table is in an invalid state for the operation

TableSchemaValidationError = 20

Table schema validation failed

Implementations

impl ErrorCode

pub fn as_u32(self) -> u32

Returns the numeric code value.

pub fn from_u32(code: u32) -> Option<Self>

Creates an ErrorCode from a numeric code.

Returns None if the code is not recognized.

Trait Implementations

impl Clone for ErrorCode

fn clone(&self) -> ErrorCode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ErrorCode

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

Formats the value using the given formatter.

impl Display for ErrorCode

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

Formats the value using the given formatter.

impl Hash for ErrorCode

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ErrorCode

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