Implementations

impl UndefOp

pub fn new(ctx: &mut Context, result_ty: Ptr<TypeObj>) -> Self

Create a new UndefOp.

Trait Implementations

impl Clone for UndefOp

fn clone(&self) -> UndefOp

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Hash for UndefOp

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 OneResultInterface for UndefOp

fn get_result(&self, ctx: &Context) -> Value

Get the single result defined by this Op.

fn result_type(&self, ctx: &Context) -> Ptr<Box<dyn Type>>

Get the type of the single result defined by this Op.

impl Op for UndefOp

fn get_operation(&self) -> Ptr<Operation>

Get the underlying IR Operation

fn get_opid(&self) -> OpId

Get this Op’s OpId

fn get_opid_static() -> OpId

Get this Op’s OpId, without self reference.

fn get_concrete_op_info() -> (fn(Ptr<Operation>) -> OpBox, TypeId)

where Self: Sized,

Get details about the concrete Op type.

fn register(ctx: &mut Context)

where Self: Sized + Parsable<Arg = Vec<(Identifier, Location)>, Parsed = OpBox>,

Register Op in Context and add it to its dialect.

fn loc(&self, ctx: &Context) -> Location

Get Op’s location

impl Parsable for UndefOp

type Arg = Vec<(Identifier, Location)>

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

type Parsed = OpBox

The type of the parsed entity.

fn parse<'__pliron_parse>( state_stream: &mut StateStream<'__pliron_parse>, arg: Self::Arg, ) -> ParseResult<'__pliron_parse, 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>>, PartialState = (), Output = Self::Parsed> + 'a>

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

impl PartialEq for UndefOp

fn eq(&self, other: &UndefOp) -> 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 Printable for UndefOp

fn fmt(&self, ctx: &Context, state: &State, fmt: &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.

impl SideEffects for UndefOp

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

Returns true if the operation has side effects, and false otherwise.

impl Verify for UndefOp

fn verify(&self, _ctx: &Context) -> Result<()>

impl Copy for UndefOp

impl Eq for UndefOp

impl NResultsInterface<1> for UndefOp
