Struct InputSignatureEntry 

pub struct InputSignatureEntry { /* private fields */ }

Value-free metadata signature for a tensor input.

Examples

use tenferro_runtime::{DType, InputSignatureEntry, LayoutClass};
use tenferro_tensor::Placement;

let entry = InputSignatureEntry::new(
    DType::F64,
    [2_usize].into_iter().collect(),
    Placement::default(),
    LayoutClass::new("tenferro.layout.strided")?,
    [1_isize].into_iter().collect(),
    Some(3),
)?;
assert_eq!(entry.dtype(), DType::F64);

Implementations

impl InputSignatureEntry

pub fn new( dtype: DType, shape: ShapeVec, placement: Placement, layout_class: LayoutClass, strides: StrideVec, alignment_log2: Option<u8>, ) -> Result<Self, InputSignatureError>

Build one value-free input signature entry.

Examples

use tenferro_runtime::{DType, InputSignatureEntry, LayoutClass};
use tenferro_tensor::Placement;

let entry = InputSignatureEntry::new(
    DType::I32,
    [4_usize].into_iter().collect(),
    Placement::default(),
    LayoutClass::new("tenferro.layout.compact")?,
    [1_isize].into_iter().collect(),
    None,
)?;
assert_eq!(entry.shape(), &[4]);

Errors

Returns InputSignatureError::ShapeStrideRankMismatch when shape and stride ranks differ, or InputSignatureError::InvalidAlignmentClass when alignment_log2 is outside the finite usize alignment lattice.

pub fn dtype(&self) -> DType

Return the dtype component.

Examples

use tenferro_runtime::{DType, InputSignatureEntry, LayoutClass};
use tenferro_tensor::Placement;

let entry = InputSignatureEntry::new(
    DType::Bool,
    [1_usize].into_iter().collect(),
    Placement::default(),
    LayoutClass::new("tenferro.layout.strided")?,
    [1_isize].into_iter().collect(),
    None,
)?;
assert_eq!(entry.dtype(), DType::Bool);

pub fn shape(&self) -> &[usize]

Return the shape component.

Examples

use tenferro_runtime::{DType, InputSignatureEntry, LayoutClass};
use tenferro_tensor::Placement;

let entry = InputSignatureEntry::new(
    DType::F64,
    [2_usize, 3].into_iter().collect(),
    Placement::default(),
    LayoutClass::new("tenferro.layout.strided")?,
    [1_isize, 2].into_iter().collect(),
    None,
)?;
assert_eq!(entry.shape(), &[2, 3]);

pub fn placement(&self) -> &Placement

Return the placement metadata component.

Examples

use tenferro_runtime::{DType, InputSignatureEntry, LayoutClass};
use tenferro_tensor::{MemoryKind, Placement};

let entry = InputSignatureEntry::new(
    DType::F64,
    [1_usize].into_iter().collect(),
    Placement::default(),
    LayoutClass::new("tenferro.layout.strided")?,
    [1_isize].into_iter().collect(),
    None,
)?;
assert_eq!(entry.placement().memory_kind, MemoryKind::UnpinnedHost);

pub fn layout_class(&self) -> &LayoutClass

Return the layout class component.

Examples

use tenferro_runtime::{DType, InputSignatureEntry, LayoutClass};
use tenferro_tensor::Placement;

let layout = LayoutClass::new("tenferro.layout.strided")?;
let entry = InputSignatureEntry::new(
    DType::F64,
    [1_usize].into_iter().collect(),
    Placement::default(),
    layout.clone(),
    [1_isize].into_iter().collect(),
    None,
)?;
assert_eq!(entry.layout_class(), &layout);

pub fn strides(&self) -> &[isize]

Return the stride metadata component.

Examples

use tenferro_runtime::{DType, InputSignatureEntry, LayoutClass};
use tenferro_tensor::Placement;

let entry = InputSignatureEntry::new(
    DType::F64,
    [2_usize].into_iter().collect(),
    Placement::default(),
    LayoutClass::new("tenferro.layout.strided")?,
    [2_isize].into_iter().collect(),
    None,
)?;
assert_eq!(entry.strides(), &[2]);

pub fn alignment_log2(&self) -> Option<u8>

Return the known alignment class, if available.

Examples

use tenferro_runtime::{DType, InputSignatureEntry, LayoutClass};
use tenferro_tensor::Placement;

let entry = InputSignatureEntry::new(
    DType::F64,
    [1_usize].into_iter().collect(),
    Placement::default(),
    LayoutClass::new("tenferro.layout.strided")?,
    [1_isize].into_iter().collect(),
    Some(3),
)?;
assert_eq!(entry.alignment_log2(), Some(3));

Trait Implementations

impl Clone for InputSignatureEntry

fn clone(&self) -> InputSignatureEntry

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InputSignatureEntry

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

Formats the value using the given formatter.

impl Eq for InputSignatureEntry

impl Hash for InputSignatureEntry

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for InputSignatureEntry

fn eq(&self, other: &InputSignatureEntry) -> 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.
