Struct StorageCastOperation 

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

A scast operation. Storage cast operation.

Convert a value from a quantized type to the corresponding signless integer storage type, or vice versa. This conversion simply involves a reinterpretation of the input bits and does not involve any data manipulation.

The following syntactic restrictions must be met:

• Operand input must be a scalar or tensor of a signless integer or !quant.uniform type.

• The result must be a scalar or tensor of a signless integer or !quant.uniform type.

• If the operand is a scalar or tensor of type integer, the result must be a scalar or tensor of type !quant.uniform, and vice versa.

• The operand and result must be both scalars or both tensors. If tensors, they must be both ranked or both unranked. If ranked, both must have the same shape, including matching static and dynamic dimensions.

• The width of the storageType parameter of the quantized type of the operand or result must match the width of the signless integer type of the operand or result.

• If the operand or result uses per-channel quantization, its !quant.uniform type must adhere to the Per-axis quantization integrity guidelines.

Examples:

// Cast a scalar quantized value into its storage type
%result = quant.scast %input : !quant.uniform<i8:f32, 2.0> to i8

// Cast a dynamically shaped tensor of quantized values into their storage type
%result = quant.scast %input : tensor<?x!quant.uniform<i8:f32, 2.0>> to tensor<?xi8>

// Cast an unranked tensor of signless integers into a quantized type using
// per-channel quantization
%result = quant.scast %input : tensor<*xi8> to tensor<*x!quant.uniform<i8:f32:1, {2.0, 3.0}>>

Trait Implementations

impl<'c> Clone for StorageCastOperation<'c>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'c> Debug for StorageCastOperation<'c>

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

Formats the value using the given formatter.

impl<'b> From<StorageCastOperation<'b>> for QuantDialectOperation<'b>

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

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

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

Converts to this type from the input type.

impl<'c> PartialEq for StorageCastOperation<'c>

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