Enum ra_ap_hir::CfgAtom

pub enum CfgAtom {
    Flag(SmolStr),
    KeyValue {
        key: SmolStr,
        value: SmolStr,
    },
}

A simple configuration value passed in from the outside.

Variants

Flag(SmolStr)

eg. #[cfg(test)]

KeyValue

eg. #[cfg(target_os = "linux")]

Note that a key can have multiple values that are all considered “active” at the same time. For example, #[cfg(target_feature = "sse")] and #[cfg(target_feature = "sse2")].

Fields

key: SmolStr

value: SmolStr

Trait Implementations

impl Extend<CfgAtom> for CfgOptions

fn extend<T>(&mut self, iter: T)

where T: IntoIterator<Item = CfgAtom>,

Extends a collection with the contents of an iterator.

fn extend_one(&mut self, item: A)

🔬This is a nightly-only experimental API. (extend_one)

Extends a collection with exactly one element.

fn extend_reserve(&mut self, additional: usize)

🔬This is a nightly-only experimental API. (extend_one)

impl From<CfgAtom> for CfgExpr

fn from(atom: CfgAtom) -> CfgExpr

Converts to this type from the input type.

impl Hash for CfgAtom

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 CfgAtom

fn cmp(&self, other: &CfgAtom) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for CfgAtom

fn eq(&self, other: &CfgAtom) -> 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.

impl PartialOrd for CfgAtom

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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