Enum Error 

#[non_exhaustive]
pub enum Error<D> {
    Decider(D),
    Transient(Transient),
    Permanent(Permanent),
    OutcomeUnknown(Failure),
    NotARevision(NotARevision),
    EmptyRange(EmptyRange),
}

Any failure of architecturekit, where D is the error of a decider, so that a function that calls several operations can pass their failures on with ?.

Every error of an operation turns into it. It holds all the cases of those, so a match on it needs a catch-all arm, and new cases may come with new operations. Where the cases of a single operation matter, match on its own error before it turns into this one.

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.

Decider(D)

See ExecuteError::Decider.

Transient(Transient)

A failure of the category Category::Transient.

Permanent(Permanent)

A failure of the category Category::Permanent.

OutcomeUnknown(Failure)

See ExecuteError::OutcomeUnknown.

NotARevision(NotARevision)

See ExecuteError::NotARevision.

EmptyRange(EmptyRange)

See ReadError::EmptyRange.

Trait Implementations

impl<D: Categorized> Categorized for Error<D>

fn category(&self) -> Option<Category>

Returns the category of the error, or None if it belongs to none.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
