Enum ErrorClass 

#[non_exhaustive]
pub enum ErrorClass {
    Transient,
    Permanent,
    Other(String),
}

An error class. Decodes open: a value other than classes is kept in ErrorClass::Other. Non-exhaustive, so a match needs a wildcard arm and adding a variant later is not a breaking change.

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.

Transient

Permanent

Other(String)

Implementations

impl ErrorClass

pub fn parse(class: &str) -> Self

pub fn as_str(&self) -> &str

pub fn effective(&self) -> Self

The class a caller acts on: an unknown class is treated as permanent, so a caller never retries what it cannot classify.

pub fn is_transient(&self) -> bool

Whether the class, as a caller acts on it, is transient.
