Enum TenantError 

#[non_exhaustive]
pub enum TenantError {
    NamespaceNotFound(String),
    NamespaceAlreadyExists(String),
    QuotaExceeded {
        namespace: String,
        resource: String,
        current: u64,

}

Tenant / namespace errors.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

NamespaceNotFound(String)

Namespace not found.

NamespaceAlreadyExists(String)

Namespace already exists.

QuotaExceeded

A namespace quota has been exceeded.

Information Disclosure

The error message deliberately includes current and limit values. This is acceptable because:

The error is only returned to authenticated, namespace-scoped callers who already have write access and can trivially infer their own usage. Operators need these values for capacity-planning and debugging. The HTTP layer maps this to a 429 response with a generic message; the detailed fields are only visible in server logs and metrics (not forwarded to the end-user response body).

Fields

namespace: String

The namespace that exceeded the quota.

resource: String

Which resource hit the limit (e.g. series_count).

current: u64

Current usage value.

limit: u64

Configured limit.

InvalidConfig(String)

Invalid namespace configuration.

Schema(SchemaError)

Schema validation error from chronix-core.

Persist(String)

The registry could not be persisted.

Its own variant because it is the server’s fault and every other variant here is the caller’s. They shared InvalidConfig, so a full disk reached an operator as 400 invalid namespace config — a message that sends them to re-read the request body while the problem is the volume.

Trait Implementations

impl Debug for TenantError

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

Formats the value using the given formatter.

impl Display for TenantError

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

Formats the value using the given formatter.

impl Error for TenantError

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<SchemaError> for TenantError

fn from(source: SchemaError) -> Self

Converts to this type from the input type.
