Struct ExtractOperation 

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

An extract operation. Extract the item at the specified index in a range.

pdl_interp.extract operations are used to extract an item from a range at the specified index. If the index is out of range, returns null.

Example:

// Extract the value at index 1 from a range of values.
%ops = pdl_interp.extract 1 of %values : !pdl.value

Implementations

impl<'c> ExtractOperation<'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>, ) -> ExtractOperationBuilder<'c, Unset, Unset, Unset>

Creates a builder.

pub fn result(&self) -> Result<OperationResult<'c, '_>, Error>

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

pub fn index(&self) -> Result<IntegerAttribute<'c>, Error>

pub fn set_index(&mut self, value: IntegerAttribute<'c>)

Trait Implementations

impl<'c> Clone for ExtractOperation<'c>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'c> Debug for ExtractOperation<'c>

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

Formats the value using the given formatter.

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

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

Converts to this type from the input type.

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

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

Converts to this type from the input type.

impl<'c> PartialEq for ExtractOperation<'c>

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