Trait Implementations

impl Clone for Context

fn clone(&self) -> Context

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for Context

fn default() -> Context

Returns the “default value” for a type.

impl Display for Context

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

Formats the value using the given formatter.

impl FromStr for Context

type Err = ParseError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Context, <Self as FromStr>::Err>

Parses a string s to return a value of this type.

impl IntoEnumIterator for Context

type Iterator = ContextIter

fn iter() -> ContextIter

impl PartialEq for Context

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl TryFrom<&str> for Context

type Error = ParseError

The type returned in the event of a conversion error.

fn try_from(s: &str) -> Result<Context, <Self as TryFrom<&str>>::Error>

Performs the conversion.

impl ValueEnum for Context

fn value_variants<'a>() -> &'a [Self]

All possible argument values, in display order.

fn to_possible_value<'a>(&self) -> Option<PossibleValue>

The canonical argument value.

fn from_str(input: &str, ignore_case: bool) -> Result<Self, String>

Parse an argument into Self.
