The vast majority of the time, the compiler deals with a fixed set of values, so it is convenient for them to be represented in an enum. However, it is possible to have arbitrary values in a target JSON file (which can be parsed when --target is specified). This might occur, for example, for an out-of-tree codegen backend that supports a value (e.g. architecture or OS) that rustc currently doesn’t know about. This variant exists as an escape hatch for such cases.

Trait Implementations

impl Clone for Env

fn clone(&self) -> Env

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Env

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Env

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'s, V> Drive<'s, V> for Env

where V: Visitor + Visit<'s, Ustr>,

fn drive_inner(&'s self, visitor: &mut V) -> ControlFlow<V::Break>

Call v.visit() on the immediate contents of self.

impl<'s, V> DriveMut<'s, V> for Env

where V: Visitor + VisitMut<'s, Ustr>,

fn drive_inner_mut(&'s mut self, visitor: &mut V) -> ControlFlow<V::Break>

Call v.visit() on the immediate contents of self.

impl<'s, V> DriveTwo<'s, V> for Env

where V: Visitor<Break: Default> + VisitTwo<'s, Ustr>,

fn drive_two_inner( &'s self, other: &'s Self, visitor: &mut V, ) -> ControlFlow<V::Break>

Call v.visit() on the immediate contents of self and other, if they correspond. If the values don’t match up, this returns Break(Default::default()).

impl Eq for Env

impl PartialEq for Env

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

Equality operator ==.

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

Inequality operator !=.

impl Serialize for Env

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
