Enum ra_ap_cfg::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 of KeyValue

key: SmolStrvalue: SmolStr

Implementations

impl CfgAtom

pub fn is_target_defined(&self) -> bool

Returns true when the atom comes from the target specification.

If this returns true, then changing this atom requires changing the compilation target. If it returns false, the atom might come from a build script or the build system.

Trait Implementations

impl Clone for CfgAtom

fn clone(&self) -> CfgAtom

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CfgAtom

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

Formats the value using the given formatter.

impl Display for CfgAtom

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

Formats the value using the given formatter.

impl Eq for CfgAtom

impl From<CfgAtom> for CfgExpr

fn from(atom: CfgAtom) -> Self

Performs the conversion.

impl Hash for CfgAtom

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

Feeds this value into the given Hasher.

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

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.

#[must_use]pub fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]pub fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]pub fn clamp(self, min: Self, max: Self) -> Self

Restrict a value to a certain interval.

impl PartialEq<CfgAtom> 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: &CfgAtom) -> bool

This method tests for !=.

impl PartialOrd<CfgAtom> for CfgAtom

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

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

#[must_use]pub fn lt(&self, other: &Rhs) -> bool

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

#[must_use]pub fn le(&self, other: &Rhs) -> bool

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

#[must_use]pub fn gt(&self, other: &Rhs) -> bool

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

#[must_use]pub fn ge(&self, other: &Rhs) -> bool
