Struct melior::ir::operation::OperationRef

pub struct OperationRef<'c, 'a> { /* private fields */ }

A reference to an operation.

Implementations

impl<'c, 'a> OperationRef<'c, 'a>

pub fn result(self, index: usize) -> Result<OperationResult<'c, 'a>, Error>

Returns a result at a position.

pub unsafe fn to_ref(&self) -> &'a Operation<'c>

Returns an operation.

This function is different from deref because the correct lifetime is kept for the return type.

Safety

The returned reference is safe to use only in the lifetime scope of the operation reference.

pub const fn to_raw(self) -> MlirOperation

Converts an operation reference into a raw object.

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

Creates an operation reference from a raw object.

Safety

A raw object must be valid.

pub unsafe fn from_option_raw(raw: MlirOperation) -> Option<Self>

Creates an optional operation reference from a raw object.

Safety

A raw object must be valid.

Trait Implementations

impl<'c, 'a> Clone for OperationRef<'c, 'a>

fn clone(&self) -> OperationRef<'c, 'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'c, 'a> Debug for OperationRef<'c, 'a>

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

Formats the value using the given formatter.

impl<'c, 'a> Deref for OperationRef<'c, 'a>

type Target = Operation<'c>

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<'c, 'a> Display for OperationRef<'c, 'a>

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

Formats the value using the given formatter.

impl<'c, 'a> PartialEq for OperationRef<'c, 'a>

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
