Enum clap::error::ContextValue

#[non_exhaustive]
pub enum ContextValue {
    None,
    Bool(bool),
    String(String),
    Strings(Vec<String>),
    Number(isize),
}

A piece of error information

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

None

ContextKind is self-sufficient, no additional information needed

Bool(bool)

A single value

String(String)

A single value

Strings(Vec<String>)

Many values

Number(isize)

A single value

Trait Implementations

impl Clone for ContextValue

fn clone(&self) -> ContextValue

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ContextValue

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

Formats the value using the given formatter.

impl PartialEq for ContextValue

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
