Struct EraseOperation 

pub struct EraseOperation<'c> { /* private fields */ }

An erase operation. Mark an input operation as erased.

pdl.erase operations are used within pdl.rewrite regions to specify that an input operation should be marked as erased. The semantics of this operation correspond with the eraseOp method on a PatternRewriter.

Example:

pdl.erase %root

Implementations

impl<'c> EraseOperation<'c>

pub fn name() -> &'static str

Returns a name.

pub fn as_operation(&self) -> &Operation<'c>

Returns a generic operation.

pub fn builder( context: &'c Context, location: Location<'c>, ) -> EraseOperationBuilder<'c, Unset>

Creates a builder.

pub fn op_value(&self) -> Result<Value<'c, '_>, Error>

Trait Implementations

impl<'c> Clone for EraseOperation<'c>

fn clone(&self) -> EraseOperation<'c>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'c> Debug for EraseOperation<'c>

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

Formats the value using the given formatter.

impl<'b> From<EraseOperation<'b>> for PdlDialectOperation<'b>

fn from(op: EraseOperation<'b>) -> Self

Converts to this type from the input type.

impl<'c> From<EraseOperation<'c>> for Operation<'c>

fn from(operation: EraseOperation<'c>) -> Self

Converts to this type from the input type.

impl<'c> PartialEq for EraseOperation<'c>

fn eq(&self, other: &EraseOperation<'c>) -> 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<'c> TryFrom<Operation<'c>> for EraseOperation<'c>

type Error = Error

The type returned in the event of a conversion error.

fn try_from(operation: Operation<'c>) -> Result<Self, Self::Error>

Performs the conversion.
