Enum ErrorKind 

pub enum ErrorKind {
    Transient,
    Client,
    Internal,
    Corrupt,
}

Fault domain classification for any framework error.

All error types implement Classify to expose their ErrorKind.

Variants

Transient

Environmental fluctuation — retry with exponential backoff.

Client

Caller error — bad request or system state; do not retry.

Internal

Framework bug or panic — do not retry; alert.

Corrupt

Data corruption — route to Dead Letter Queue; manual intervention required.

Trait Implementations

impl Clone for ErrorKind

fn clone(&self) -> ErrorKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ErrorKind

impl Debug for ErrorKind

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

Formats the value using the given formatter.

impl Eq for ErrorKind

impl PartialEq for ErrorKind

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