Enum Action 

#[non_exhaustive]
pub enum Action {
    Set,
    App,
    Pop,
    Cnt,
    Clr,
    Null,
}

The default action type for option value saving, see process.

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.

Set

Set and replace current value of AnyValue

App

Append value into AnyValue

Pop

Pop value from AnyValue

Cnt

Saving the count of arguments into AnyValue

Clr

Clear the value of AnyValue

Null

Do nothing

Trait Implementations

impl Clone for Action

fn clone(&self) -> Action

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Action

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

Formats the value using the given formatter.

impl Default for Action

fn default() -> Action

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Action

fn deserialize<__D>( __deserializer: __D, ) -> Result<Action, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Action

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

Formats the value using the given formatter.

impl Ord for Action

fn cmp(&self, other: &Action) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Action

fn eq(&self, other: &Action) -> 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 PartialOrd for Action

fn partial_cmp(&self, other: &Action) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for Action

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<Set, Val> Store<Set, Val> for Action

where Val: ErasedTy, SetOpt<Set>: Opt, Set: Set,

Default store using for store value to ValStorer. It will store OsString and Val if val is Some(Val), otherwise do nothing.

Note: The ValStorer internal using an vec saving the option value.

• Action::Set : Set the option value to vec![ val ].

• Action::App : Append the value to value vector.

• Action::Pop : Pop last value from value vector.

• Action::Cnt : Count the value and save the count as vec![cnt].

• Action::Clr : Clear all the value from value vector.

• Action::Null : Do nothing.

type Ret = bool

type Error = Error

fn process( &mut self, uid: Uid, set: &mut Set, raw: Option<&OsStr>, val: Option<Val>, ) -> Result<Self::Ret, Self::Error>
