Enum CliError 

pub enum CliError {
    Usage(String),
    Refusals(Vec<Refusal>),
    Engine(EngineError),
    BadTempo(String),
    BadProbe(String),
    Io(String),
    NotFound(String),
    Conflict {
        by: &'static str,
        message: String,
    },
    LintRefused(Vec<LintViolation>),
}

Every expected failure mode this crate can hit; none of them a panic.

Variants

Usage(String)

Refusals(Vec<Refusal>)

Engine(EngineError)

BadTempo(String)

BadProbe(String)

Io(String)

NotFound(String)

A path the caller named that nothing answers for; an Io is one that is there.

Conflict

A name already taken, as opposed to an Io the filesystem raised.

Fields

by: &'static str

message: String

LintRefused(Vec<LintViolation>)

Every LintViolation the scan found, not just the first.

Implementations

impl CliError

pub fn exit_code(&self) -> u8

This repo’s cli standard exit-code table, by failure category.

pub fn code(&self) -> &'static str

The top-level error.code, per the standard’s error-code table.

pub fn message(&self) -> String

pub fn diagnostics(&self) -> Vec<Diagnostic>

Per-finding detail; empty only where the failure has no subject to locate it against.

Trait Implementations

impl Debug for CliError

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

Formats the value using the given formatter.

impl Display for CliError

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

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.
