Enum UsedBy 

pub enum UsedBy {
    Compiler,
    Linker,
}

There are three valid forms of the attribute: #[used], which is semantically equivalent to #[used(linker)] except that the latter is currently unstable. #[used(compiler)] #[used(linker)]

Trait Implementations

impl Clone for UsedBy

fn clone(&self) -> UsedBy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UsedBy

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

Formats the value using the given formatter.

impl<__D: SpanDecoder> Decodable<__D> for UsedBy

fn decode(__decoder: &mut __D) -> Self

impl<__E: SpanEncoder> Encodable<__E> for UsedBy

fn encode(&self, __encoder: &mut __E)

impl Hash for UsedBy

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

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<__CTX> HashStable<__CTX> for UsedBy

where __CTX: HashStableContext,

fn hash_stable(&self, __hcx: &mut __CTX, __hasher: &mut StableHasher)

impl PartialEq for UsedBy

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PrintAttribute for UsedBy

fn should_render(&self) -> bool

Whether or not this will render as something meaningful, or if it’s skipped (which will force the containing struct to also skip printing a comma and the field name).

fn print_attribute(&self, __p: &mut Printer)

impl Copy for UsedBy

impl Eq for UsedBy

impl StructuralPartialEq for UsedBy

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
