Enum PortErrorKind 

#[non_exhaustive]
pub enum PortErrorKind {
    Conflict,
    Unavailable,
    Other,
}

The general category of a PortError, so callers can react (e.g. retry) without inspecting the underlying error.

Examples

See PortError for a worked example of matching on a PortErrorKind.

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.

Conflict

The operation conflicted with concurrent state (e.g. a stale version on Save).

Unavailable

The port is temporarily unreachable (e.g. a network/connection failure); retrying later may succeed.

Other

Any failure not covered by a more specific kind.
