Struct DagInit 

pub struct DagInit<'a> { /* private fields */ }

Implementations

impl<'a> DagInit<'a>

pub unsafe fn from_raw(raw: TableGenTypedInitRef) -> Self

Creates a new init from a raw object.

Safety

The raw object must be valid.

pub fn dump(self)

Dumps this init to stderr (for debugging).

impl<'a> DagInit<'a>

pub fn args(self) -> DagIter<'a>

Returns an iterator over the arguments of the dag.

The iterator yields tuples (Option<&str>, TypedInit) where the first element is the argument name, or None if the argument is unnamed (e.g. positional args like (add r0, r1, r2)).

Use DagInit::num_args and DagInit::get for indexed access if you only need values.

pub fn operator(self) -> Record<'a>

Returns the operator of the dag as a Record.

pub fn num_args(self) -> usize

Returns the number of arguments for this dag.

pub fn name(self, index: usize) -> Option<&'a str>

Returns the name of the argument at the given index.

pub fn arg_no(self, name: &str) -> Option<usize>

Returns the argument index for the given name, or None if not found.

pub fn get(self, index: usize) -> Option<TypedInit<'a>>

Returns the argument at the given index.

Trait Implementations

impl<'a> Clone for DagInit<'a>

fn clone(&self) -> DagInit<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for DagInit<'a>

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

Formats the value using the given formatter.

impl<'a> Display for DagInit<'a>

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

Formats the value using the given formatter.

impl Hash for DagInit<'_>

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<'a> PartialEq for DagInit<'a>

fn eq(&self, other: &DagInit<'a>) -> 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<'a> TryFrom<RecordValue<'a>> for DagInit<'a>

type Error = SourceError<TableGenError>

The type returned in the event of a conversion error.

fn try_from(record_value: RecordValue<'a>) -> Result<Self, Self::Error>

Performs the conversion.

impl<'a> TryFrom<TypedInit<'a>> for DagInit<'a>

type Error = SourceError<TableGenError>

The type returned in the event of a conversion error.

fn try_from(value: TypedInit<'a>) -> Result<Self, Self::Error>

Performs the conversion.
