Enum Attribute

pub enum Attribute {
    NonExhaustive,
    MustUse {
        reason: Option<String>,
    },
    ExportName(String),
    LinkSection(String),
    AutomaticallyDerived,
    Repr(AttributeRepr),
    NoMangle,
    TargetFeature {
        enable: Vec<String>,
    },
    Other(String),
}

An attribute, e.g. #[repr(C)]

This doesn’t include:

• #[doc = "Doc Comment"] or /// Doc comment. These are in Item::docs instead.
• #[deprecated]. These are in Item::deprecation instead.

Variants

NonExhaustive

#[non_exhaustive]

MustUse

#[must_use]

Fields

reason: Option<String>

ExportName(String)

#[export_name = "name"]

LinkSection(String)

#[link_section = "name"]

AutomaticallyDerived

#[automatically_derived]

Repr(AttributeRepr)

#[repr]

NoMangle

#[no_mangle]

TargetFeature

#[target_feature(enable = “feature1”, enable = “feature2”)]

Fields

enable: Vec<String>

Other(String)

Something else.

Things here are explicitly not covered by the FORMAT_VERSION constant, and may change without bumping the format version.

As an implementation detail, this is currently either:

1. A HIR debug printing, like "#[attr = Optimize(Speed)]"
2. The attribute as it appears in source form, like "#[optimize(speed)]".

Trait Implementations

impl Clone for Attribute

fn clone(&self) -> Attribute

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Attribute

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Attribute

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Attribute

fn eq(&self, other: &Attribute) -> 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 Serialize for Attribute

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Attribute

impl StructuralPartialEq for Attribute
