Enum WrapperError 

pub enum WrapperError {
    Command(CommandRunError),
}

The one thing that can genuinely fail a wrapper run: the docker subprocess could not be spawned at all (e.g. the binary is not on PATH). Everything cache-side degrades to a plain real build (D6) and so is not a WrapperError — see run_wrapper’s fall-through contract. A failing docker build is likewise not a WrapperError; it is the typed WrapperOutcome::BuildFailed inside an Ok receipt. Surfaced as a typed error, never a panic.

Trait Implementations

impl Debug for WrapperError

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

Formats the value using the given formatter.

impl Display for WrapperError

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

Formats the value using the given formatter.

impl Error for WrapperError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

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

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<CommandRunError> for WrapperError

fn from(source: CommandRunError) -> Self

Converts to this type from the input type.
