Struct AttributeSet 

pub struct AttributeSet(/* private fields */);

An AttributeSet is a uniqued collection of attributes associated with some IR entity

Implementations

impl AttributeSet

pub const fn new() -> Self

Get a new, empty AttributeSet

pub fn insert( &mut self, name: impl Into<Symbol>, value: Option<impl AttributeValue>, )

Insert a new Attribute in this set by name and value

pub fn set(&mut self, attr: Attribute)

Adds attr to this set

pub fn mark_intrinsic(&mut self, key: impl Into<Symbol>)

pub fn remove(&mut self, name: impl Into<Symbol>)

Remove an Attribute by name from this set

pub fn has(&self, key: impl Into<Symbol>) -> bool

Determine if the named Attribute is present in this set

pub fn get_any(&self, key: impl Into<Symbol>) -> Option<&dyn AttributeValue>

Get the AttributeValue associated with the named Attribute

pub fn get_any_mut( &mut self, key: impl Into<Symbol>, ) -> Option<&mut dyn AttributeValue>

Get the AttributeValue associated with the named Attribute

pub fn get<V>(&self, key: impl Into<Symbol>) -> Option<&V>

where V: AttributeValue,

Get the value associated with the named Attribute as a value of type V, or None.

pub fn get_mut<V>(&mut self, key: impl Into<Symbol>) -> Option<&mut V>

where V: AttributeValue,

Get the value associated with the named Attribute as a mutable value of type V, or None.

pub fn iter(&self) -> impl Iterator<Item = &Attribute> + '_

Iterate over each Attribute in this set

Trait Implementations

impl Clone for AttributeSet

fn clone(&self) -> AttributeSet

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AttributeSet

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

Formats the value using the given formatter.

impl Default for AttributeSet

fn default() -> AttributeSet

Returns the “default value” for a type.

impl FromIterator<(Symbol, Option<Box<dyn AttributeValue>>)> for AttributeSet

fn from_iter<T>(attrs: T) -> Self

where T: IntoIterator<Item = (Symbol, Option<Box<dyn AttributeValue>>)>,

Creates a value from an iterator.

impl FromIterator<Attribute> for AttributeSet

fn from_iter<T>(attrs: T) -> Self

where T: IntoIterator<Item = Attribute>,

Creates a value from an iterator.

impl Hash for AttributeSet

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 PartialEq for AttributeSet

fn eq(&self, other: &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.
