pub enum QuotaError {
    NamespaceAlreadyExists(String),
    NamespaceNotFound(String),
    ObjectNotFound(String),
    ObjectAlreadyExists(String),
    GlobalLimitExceeded {
        used: u64,
        limit: u64,
    },
    HardLimitExceeded {
        namespace: String,
    },
}

Errors returned by StorageQuotaManager operations.

Variants

NamespaceAlreadyExists(String)

A namespace with this identifier is already registered.

NamespaceNotFound(String)

No namespace with this identifier is registered.

ObjectNotFound(String)

No object with this identifier is tracked.

ObjectAlreadyExists(String)

An object with this identifier is already tracked.

GlobalLimitExceeded

This allocation would exceed the global byte ceiling.

Fields

used: u64

Bytes that would be used after this allocation.

limit: u64

Configured global limit.

HardLimitExceeded

Namespace-level hard limit exceeded (byte or object count).

Fields

namespace: String

Namespace name.

Trait Implementations

impl Clone for QuotaError

fn clone(&self) -> QuotaError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QuotaError

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

Formats the value using the given formatter.

impl Display for QuotaError

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

Formats the value using the given formatter.

impl Error for QuotaError

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 QuotaError

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