Implementations

impl BoolOrAuto

pub fn as_bool(self) -> Option<bool>

Returns the explicitly set boolean value, or None

use tor_config::BoolOrAuto;

fn calculate_default() -> bool { //...
let bool_or_auto: BoolOrAuto = // ...
let _: bool = bool_or_auto.as_bool().unwrap_or_else(|| calculate_default());

Trait Implementations

impl Clone for BoolOrAuto

fn clone(&self) -> BoolOrAuto

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BoolOrAuto

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

Formats the value using the given formatter.

impl Default for BoolOrAuto

fn default() -> BoolOrAuto

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for BoolOrAuto

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for BoolOrAuto

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for BoolOrAuto

fn cmp(&self, other: &BoolOrAuto) -> 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 BoolOrAuto

fn eq(&self, other: &BoolOrAuto) -> 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 BoolOrAuto

fn partial_cmp(&self, other: &BoolOrAuto) -> 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 BoolOrAuto

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 TryFrom<BoolOrAutoSerde> for BoolOrAuto

type Error = InvalidBoolOrAuto

The type returned in the event of a conversion error.

fn try_from( pls: BoolOrAutoSerde, ) -> Result<BoolOrAuto, <BoolOrAuto as TryFrom<BoolOrAutoSerde>>::Error>

Performs the conversion.

impl Eq for BoolOrAuto

impl StructuralPartialEq for BoolOrAuto

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
