Enum RunErrorKind 

#[non_exhaustive]
pub enum RunErrorKind {
    ClapUsage,
    DefaultCommand,
    Handler,
    Hook(HookPhase),
    Render,
    FinalWrite(OutputKind),
    External,
}

Typed origin for an unsuccessful framework run.

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.

ClapUsage

Clap rejected the command line.

DefaultCommand

A default-command resolver named a command the CLI does not have.

Handler

The application handler returned an error.

Hook(HookPhase)

A hook failed in the identified phase. Pipe failures are post-output hooks.

Render

Handler data serialization or presentation rendering failed.

FinalWrite(OutputKind)

A framework-owned file/stdout write failed.

External

The application declared a failure from an authoritative external operation.
