Enum InfraErrorKind 

#[non_exhaustive]
pub enum InfraErrorKind {
    Connection,
    Timeout,
    Query,
    DataCorruption,
    Other,
}

Classification of infrastructure failures.

Used to distinguish retriable (Connection, Timeout) from non-retriable (Query, DataCorruption) infrastructure errors without string parsing.

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.

Connection

Network or pool connection failure (retriable).

Timeout

Operation timed out (retriable).

Query

Query or command failed (not retriable).

DataCorruption

Stored data is corrupt or unparsable.

Other

Uncategorised infrastructure error.

Implementations

impl InfraErrorKind

pub fn is_retriable(self) -> bool

Returns true for errors that are typically transient and worth retrying.

Trait Implementations

impl Clone for InfraErrorKind

fn clone(&self) -> InfraErrorKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InfraErrorKind

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

Formats the value using the given formatter.

impl Display for InfraErrorKind

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

Formats the value using the given formatter.

impl PartialEq for InfraErrorKind

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