Struct Attributes 

pub struct Attributes { /* private fields */ }

A list of function attributes.

Attributes can be either named (e.g., @deprecated) or grouped (e.g., @[attribute1, attribute2()]).

Implementations

impl Attributes

pub fn new() -> Self

Creates a new empty list of attributes.

pub fn with_attribute(self, attribute: impl Into<Attribute>) -> Self

Adds an attribute to this list of attributes.

pub fn append_attribute(&mut self, attribute: impl Into<Attribute>)

Appends an attribute to this list of attributes.

Empty attribute groups are silently ignored.

pub fn iter_attributes(&self) -> impl Iterator<Item = &Attribute>

Returns an iterator over the attributes in this list.

pub fn iter_mut_attributes(&mut self) -> impl Iterator<Item = &mut Attribute>

Returns a mutable iterator over the attributes in this list.

pub fn clear_attributes(&mut self)

Clears all attributes.

pub fn is_empty(&self) -> bool

Returns whether this list of attributes is empty.

pub fn len(&self) -> usize

Returns the number of attributes in this list.

pub fn has_attribute(&self, name: &str) -> bool

Checks if an attribute with the given name exists in this list.

pub fn filter_attributes<F>(&mut self, predicate: F)

where F: Fn(&Attribute) -> bool,

Filters attributes based on a predicate, keeping only those that return true. The predicate receives an immutable reference to each attribute.

pub fn filter_mut_attributes<F>(&mut self, predicate: F)

where F: FnMut(&mut Attribute) -> bool,

Filters attributes based on a mutable predicate, keeping only those that return true. The predicate receives a mutable reference to each attribute, allowing modifications.

pub fn clear_comments(&mut self)

Clears all comments from the tokens in this node.

pub fn clear_whitespaces(&mut self)

Clears all whitespaces information from the tokens in this node.

Trait Implementations

impl Clone for Attributes

fn clone(&self) -> Attributes

Returns a duplicate 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, other: &Attributes) -> 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.
