Struct DeclSpecs 

pub struct DeclSpecs {
    pub storage: Option<StorageClass>,
    pub thread_local: bool,
    pub constexpr: bool,
    pub ty: TypeSpec,
    pub quals: Quals,
    pub func: FuncSpecs,
    pub align: Option<AlignSpec>,
    pub attrs: AttrList,
    pub span: Span,
}

Everything a declaration says before its first declarator.

Fields

storage: Option<StorageClass>

The storage class, of which there may be at most one.

thread_local: bool

Whether _Thread_local was written, which is separate because it is a storage class specifier that may be combined with another.

constexpr: bool

Whether constexpr was written, which is separate for the same reason: C23 6.7.1 lets it stand beside auto, register or static, and static constexpr int x = 1; is a declaration people write.

ty: TypeSpec

What type was named.

quals: Quals

The qualifiers, which may be written before or after the type.

func: FuncSpecs

inline and _Noreturn.

align: Option<AlignSpec>

alignas, of which there may be several, of which the strictest wins. Only the first is kept here; the rest are in the side table alongside it.

attrs: AttrList

Attributes that appertain to the declaration as a whole.

span: Span

From the first specifier to the last.

Implementations

impl DeclSpecs

pub const fn empty(span: Span) -> DeclSpecs

A specifier list with nothing in it, which is what the parser starts from.

pub const fn is_typedef(&self) -> bool

Whether this declares type names rather than objects.

pub const fn deduces(&self) -> Option<Deduction>

Which spelling asked for a type deduced from an initializer, if either did.
