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 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

pub fn clone(&self) -> CfgAtom

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CfgAtom

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

Formats the value using the given formatter.

impl Display for CfgAtom

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

Formats the value using the given formatter.

impl From<CfgAtom> for CfgExpr

pub fn from(atom: CfgAtom) -> CfgExpr

Performs the conversion.

impl Hash for CfgAtom

pub 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, 

Feeds a slice of this type into the given Hasher.

impl Ord for CfgAtom

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

This method returns an Ordering between self and other.

#[must_use]

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

Compares and returns the maximum of two values.

#[must_use]

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

Compares and returns the minimum of two values.

#[must_use]

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

Restrict a value to a certain interval.

impl PartialEq<CfgAtom> for CfgAtom

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

This method tests for self and other values to be equal, and is used by ==.

pub fn ne(&self, other: &CfgAtom) -> bool

This method tests for !=.

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

#[must_use]

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]

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