Struct Attributes

pub(crate) struct Attributes {
    pub(crate) doc_strings: Vec<DocFragment>,
    pub(crate) other_attrs: AttrVec,
}

The attributes on an Item, including attributes like #[derive(...)] and #[inline], as well as doc comments.

Fields

doc_strings: Vec<DocFragment>

other_attrs: AttrVec

Implementations

impl Attributes

pub(crate) fn lists( &self, name: Symbol, ) -> impl Iterator<Item = MetaItemInner> + '_

pub(crate) fn has_doc_flag(&self, flag: Symbol) -> bool

pub(crate) fn is_doc_hidden(&self) -> bool

pub(crate) fn from_ast(attrs: &[Attribute]) -> Attributes

pub(crate) fn from_ast_with_additional( attrs: &[Attribute], (additional_attrs, def_id): (&[Attribute], DefId), ) -> Attributes

pub(crate) fn from_ast_iter<'a>( attrs: impl Iterator<Item = (&'a Attribute, Option<DefId>)>, doc_only: bool, ) -> Attributes

pub(crate) fn doc_value(&self) -> String

Combine all doc strings into a single value handling indentation and newlines as needed.

pub(crate) fn opt_doc_value(&self) -> Option<String>

Combine all doc strings into a single value handling indentation and newlines as needed. Returns None is there’s no documentation at all, and Some("") if there is some documentation but it is empty (e.g. #[doc = ""]).

pub(crate) fn get_doc_aliases(&self) -> Box<[Symbol]>

Trait Implementations

impl Clone for Attributes

fn clone(&self) -> Attributes

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Attributes

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

Formats the value using the given formatter.

impl Default for Attributes

fn default() -> Attributes

Returns the “default value” for a type.

impl PartialEq for Attributes

fn eq(&self, rhs: &Self) -> 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 Eq for Attributes

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.
