Struct SwitchAttributeOperation 

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

A switch_attribute operation. Switch on the value of an Attribute.

pdl_interp.switch_attribute operations compare the value of a given attribute with a set of constant attributes. If the value matches one of the provided case values the destination for that case value is taken, otherwise the default destination is taken.

Example:

pdl_interp.switch_attribute %attr to [10, true](^10Dest, ^trueDest) -> ^defaultDest

Implementations

impl<'c> SwitchAttributeOperation<'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>, ) -> SwitchAttributeOperationBuilder<'c, Unset, Unset, Unset, Unset>

Creates a builder.

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

pub fn default_dest(&self) -> Result<BlockRef<'c, '_>, Error>

pub fn cases(&self) -> impl Iterator<Item = BlockRef<'c, '_>>

pub fn case_values(&self) -> Result<ArrayAttribute<'c>, Error>

pub fn set_case_values(&mut self, value: ArrayAttribute<'c>)

Trait Implementations

impl<'c> Clone for SwitchAttributeOperation<'c>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'c> Debug for SwitchAttributeOperation<'c>

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

Formats the value using the given formatter.

impl<'b> From<SwitchAttributeOperation<'b>> for PdlInterpDialectOperation<'b>

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

Converts to this type from the input type.

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

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

Converts to this type from the input type.

impl<'c> PartialEq for SwitchAttributeOperation<'c>

fn eq(&self, other: &SwitchAttributeOperation<'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 SwitchAttributeOperation<'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.
