Struct midenc_hir::AttributeSet

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

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

Implementations

impl AttributeSet

pub fn new() -> Self

Get a new, empty AttributeSet

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

where Symbol: Borrow<Q>, Q: Ord + ?Sized,

Remove an Attribute by name from this set

pub fn has<Q>(&self, key: &Q) -> bool

where Symbol: Borrow<Q>, Q: Ord + ?Sized,

Determine if the named Attribute is present in this set

pub fn get<Q>(&self, key: &Q) -> Option<&AttributeValue>

where Symbol: Borrow<Q>, Q: Ord + ?Sized,

Get the AttributeValue associated with the named Attribute

pub fn get_bool<Q>(&self, key: &Q) -> Option<bool>

where Symbol: Borrow<Q>, Q: Ord + ?Sized,

Get the value associated with the named Attribute as a boolean, or None.

pub fn get_int<Q>(&self, key: &Q) -> Option<isize>

where Symbol: Borrow<Q>, Q: Ord + ?Sized,

Get the value associated with the named Attribute as an integer, or None.

pub fn get_symbol<Q>(&self, key: &Q) -> Option<Symbol>

where Symbol: Borrow<Q>, Q: Ord + ?Sized,

Get the value associated with the named Attribute as a Symbol, 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 copy 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, AttributeValue)> for AttributeSet

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

where T: IntoIterator<Item = (Symbol, 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: &AttributeSet) -> 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.
