Enum Target 

pub enum Target<Value> {
    Os(Value),
    Family(Value),
    Arch(Value),
}

A cfg condition for targeting an OS, OS family, or architecture. For example:

let function = FunctionDef {
  mods: NoOpSeq,
  name: Str("conditional_func"),
  args: NoOpSeq,
  return_type: Str("()"),
  where_conds: NoOpSeq,
  body: FunctionBodyDeclare
}.with_attributes(
  SingularSeq(Cfg(Target::Os(Str("linux"))))
);
let string = InMemoryOutput::print_output(EmptyContext, &function);
assert_eq!("#[cfg(target_os = \"linux\")]\nfn conditional_func() -> ();\n", string);

Variants

Os(Value)

Family(Value)

Arch(Value)

Trait Implementations

impl<Value: Clone> Clone for Target<Value>

fn clone(&self) -> Target<Value>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<Value: Debug> Debug for Target<Value>

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

Formats the value using the given formatter.

impl<O, Value> Writable<O> for Target<Value>

where O: Output, Value: Writable<O>,

async fn write_to(&self, output: &mut O) -> Result<(), O::Error>

Writes to the output. Returns the output’s error upon failure.
