Enum FrontError 

pub enum FrontError {
    Diagnostics(Vec<Diag>),
    Core(CoreError),
}

Outcome of a front-end stage: diagnostics (user fault, exit 2 when any is an error) or a non-diagnostic core failure.

Variants

Diagnostics(Vec<Diag>)

Structured findings to render (at least one has Severity::Error).

Core(CoreError)

An IO or internal failure outside the diagnostics model.

Implementations

impl FrontError

pub fn exit_code(&self) -> ExitCode

The stable exit code for this failure (ADR-0009).

Trait Implementations

impl Debug for FrontError

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

Formats the value using the given formatter.

impl Display for FrontError

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

Formats the value using the given formatter.

impl Error for FrontError

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<CoreError> for FrontError

fn from(source: CoreError) -> Self

Converts to this type from the input type.
