Struct CliError 

pub struct CliError {
    pub rule: CliErrorRule,
    pub command_path: String,
    pub argument_names: Vec<String>,
    pub message: String,
    pub hint: String,
}

Structured CLI-resolution error. It never contains raw argument values.

Fields

rule: CliErrorRule

command_path: String

argument_names: Vec<String>

message: String

hint: String

Implementations

impl CliError

pub const fn exit_code(&self) -> u8

Fixed process exit status for every closed-world CLI error.

Derived rather than stored: every rule in CliErrorRule exits 2, and a field would only be somewhere for that to drift.

Trait Implementations

impl Clone for CliError

fn clone(&self) -> CliError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

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 Eq for CliError

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 PartialEq for CliError

fn eq(&self, other: &CliError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
