Enum CliError 

pub enum CliError {
    NotImplemented {
        what: &'static str,
        hint: &'static str,
    },
    NotInWorkspace {
        searched_from: PathBuf,
    },
    Io(Error),
    Other {
        message: String,
        exit_code: u8,
    },
    Silent {
        exit_code: u8,
    },
}

Top-level CLI failure mode.

Variants

NotImplemented

A defined subcommand whose body has not yet landed. The hint field is appended to the message so the user knows where to look for the planned design / when to expect it.

Fields

what: &'static str

hint: &'static str

NotInWorkspace

The current working directory is not inside an Aristo workspace (no aristo.toml found by walking upward).

Fields

searched_from: PathBuf

Io(Error)

I/O failure during file read/write.

Other

Catch-all for command-specific errors that carry their own message and exit code. Use when no structured variant fits and the message is the user-facing diagnostic (e.g. aristo lang’s “no supported language detected”).

Fields

message: String

exit_code: u8

Silent

Non-success exit where the command has already printed its own human-readable output (e.g. aristo lint --check listing findings). Lib’s top-level wrapper skips the generic error: ... line for this variant.

Fields

exit_code: u8

Implementations

impl CliError

pub fn is_silent(&self) -> bool

True iff the error wants the top-level wrapper to skip its generic error: ... print (because the command already produced its own structured output).

impl CliError

pub fn exit_code(&self) -> u8

Process exit code for this error class.

Trait Implementations

impl Debug for CliError

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

Formats the value using the given formatter.

impl Display for CliError

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

Formats the value using the given formatter.

impl Error for CliError

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<Error> for CliError

fn from(e: Error) -> Self

Converts to this type from the input type.
