Struct Cfg

pub struct Cfg {
    pub key: SmolStr,
    pub value: Option<SmolStr>,
}

Option for the #[cfg(...)] language attribute.

Fields

value: Option<SmolStr>

Implementations

impl Cfg

pub fn name(name: impl Into<SmolStr>) -> Self

Creates an cfg option that is matchable as #[cfg(name)].

pub fn kv(key: impl Into<SmolStr>, value: impl Into<SmolStr>) -> Self

Creates an cfg option that is matchable as #[cfg(key: "value")].

Trait Implementations

impl Clone for Cfg

fn clone(&self) -> Cfg

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Cfg

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Cfg

fn deserialize<D: Deserializer<'de>>(deserializer: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl Display for Cfg

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

Formats the value using the given formatter.

impl FromIterator<Cfg> for CfgSet

fn from_iter<T: IntoIterator<Item = Cfg>>(iter: T) -> Self

Creates a value from an iterator.

impl Hash for Cfg

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

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 Cfg

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

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

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

fn serialize<S: Serializer>(&self, serializer: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.
