Struct LlvmAttributesAttr 

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

LLVM attributes at one attribute index.

An attribute index can be a parameter from 1 to N, or one of LLVM_ATTRIBUTE_FUNCTION_INDEX or LLVM_ATTRIBUTE_RETURN_INDEX.

Printed as ["nounwind", "alignstack" = 16, "target-cpu" = "x86-64"].

Implementations

impl LlvmAttributesAttr

pub fn new() -> Self

No attributes.

pub fn get(&self, name: &str) -> Option<&LlvmAttrValue>

The value of the attribute named name, if it is present.

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

True if the attribute named name is present.

pub fn set(&mut self, name: impl Into<String>, value: LlvmAttrValue)

Set the attribute named name to value, replacing any existing value.

pub fn remove(&mut self, name: &str)

Remove the attribute named name, if it is present.

pub fn is_empty(&self) -> bool

True if there are no attributes.

pub fn iter(&self) -> impl Iterator<Item = (&str, &LlvmAttrValue)>

Iterate over (name, value) pairs.

Trait Implementations

impl Attribute for LlvmAttributesAttr

fn hash_attr(&self) -> TypeValueHash

Compute and get the hash for this instance of Self. Hash collisions can be a possibility.

fn eq_attr(&self, other: &dyn Attribute) -> bool

Is self equal to an other Attribute?

fn get_attr_id(&self) -> AttrId

Get an Attribute’s static name. This is not per instantnce. It is mostly useful for printing and parsing the attribute.

fn get_attr_id_static() -> AttrId

Same as get_attr_id, but without the self reference.

fn register<A>(ctx: &mut Context)

where A: Attribute, Self: Sized + Parsable<Arg = (), Parsed = A>,

Register this attribute’s AttrId in the dialect it belongs to.

impl Clone for LlvmAttributesAttr

fn clone(&self) -> LlvmAttributesAttr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LlvmAttributesAttr

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

Formats the value using the given formatter.

impl Default for LlvmAttributesAttr

fn default() -> LlvmAttributesAttr

Returns the “default value” for a type.

impl Eq for LlvmAttributesAttr

impl Hash for LlvmAttributesAttr

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 OutlinedAttr for LlvmAttributesAttr

Always printed outlined.

fn outline(&self, _ctx: &Context) -> bool

Whether this attribute instance should be printed in the outlined attributes section.

impl Parsable for LlvmAttributesAttr

type Arg = ()

Type of the argument that must be passed to the parser.

type Parsed = LlvmAttributesAttr

The type of the parsed entity.

fn parse<'a>( state_stream: &mut StateStream<'a>, _arg: Self::Arg, ) -> ParseResult<'a, Self::Parsed>

Define a parser using existing combinators and call into on [Parser::parse_stream] to get the final ParseResult. Use state_stream.state as necessary.

fn parser<'a>( arg: Self::Arg, ) -> Box<dyn Parser<Stream<Stream<Stream<Stream<IteratorStream<CharIterator<'a>>, SourcePosition>>>, State<'a>>, Output = Self::Parsed, PartialState = ()> + 'a>

where Self::Parsed: 'a,

Get a parser combinator that can work on StateStream as its input.

impl PartialEq for LlvmAttributesAttr

fn eq(&self, other: &LlvmAttributesAttr) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl Printable for LlvmAttributesAttr

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

fn disp<'t, 'c>(&'t self, ctx: &'c Context) -> Box<dyn Display + 'c>

where 't: 'c,

Get a Display’able object from the given Context and default State.

fn print<'t, 'c>( &'t self, ctx: &'c Context, state: &State, ) -> Box<dyn Display + 'c>

where 't: 'c,

Get a Display’able object from the given Context and State.
