Enum ErrorCategory 

pub enum ErrorCategory {
    Timeout,
    Connection,
    Serialization,
    Permission,
    Validation,
    NotFound,
    RateLimit,
    Unknown,
}

Error categories for consistent metric labeling.

This enum provides a fixed set of error types to prevent cardinality explosion from using free-form error messages as labels.

Variants

Timeout

Timeout error (operation exceeded time limit)

Connection

Connection error (network, TCP, DNS failures)

Serialization

Serialization error (JSON, BSON, encoding failures)

Permission

Permission error (authentication, authorization failures)

Validation

Validation error (invalid data, schema violations)

NotFound

Not found error (resource doesn’t exist)

RateLimit

Rate limit error (throttling, quota exceeded)

Unknown

Unknown error (unclassified)

Implementations

impl ErrorCategory

pub const fn as_str(&self) -> &'static str

Returns the error category as a static string for metrics labels.

Trait Implementations

impl Clone for ErrorCategory

fn clone(&self) -> ErrorCategory

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ErrorCategory

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

Formats the value using the given formatter.

impl Hash for ErrorCategory

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 ErrorCategory

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