struct

DimList

This type represents a list of dimensions. Each dimension may have a static value or not have a value, which represents a dynamic dimension.

Fields​

  • ​value (VariadicList[Dim]): The underlying storage for the list of dimensions.

Implemented traits​

AnyType, Sized, Stringable

Methods​

__init__​

__init__(values: Tuple[Int]) -> Self

Creates a dimension list from the given list of values.

Args:

  • ​values (Tuple[Int]): The initial dim values list.

Returns:

A dimension list.

__init__(values: Tuple[Int, Int]) -> Self

Creates a dimension list from the given list of values.

Args:

  • ​values (Tuple[Int, Int]): The initial dim values list.

Returns:

A dimension list.

__init__(values: Tuple[Int, Int, Int]) -> Self

Creates a dimension list from the given list of values.

Args:

  • ​values (Tuple[Int, Int, Int]): The initial dim values list.

Returns:

A dimension list.

__init__(values: VariadicList[Dim]) -> Self

Creates a dimension list from the given list of values.

Args:

  • ​values (VariadicList[Dim]): The initial dim values list.

Returns:

A dimension list.

__init__(*values: Dim) -> Self

Creates a dimension list from the given Dim values.

Args:

  • ​*values (Dim): The initial dim values.

Returns:

A dimension list.

__len__​

__len__(self: Self) -> Int

Gets the size of the DimList.

Returns:

The number of elements in the DimList.

get​

get[i: Int](self: Self) -> Int

Gets the static dimension value at a specified index.

Parameters:

  • ​i (Int): The dimension index.

Returns:

The static dimension value at the specified index.

at​

at[i: Int](self: Self) -> Dim

Gets the dimension at a specified index.

Parameters:

  • ​i (Int): The dimension index.

Returns:

The dimension at the specified index.

has_value​

has_value[i: Int](self: Self) -> Bool

Returns True if the dimension at the given index has a static value.

Parameters:

  • ​i (Int): The dimension index.

Returns:

Whether the specified dimension has a static value.

product​

product[length: Int](self: Self) -> Dim

Computes the product of all the dimensions in the list.

If any are dynamic, the result is a dynamic dimension value.

Parameters:

  • ​length (Int): The number of elements in the list.

Returns:

The product of all the dimensions.

product_range​

product_range[start: Int, end: Int](self: Self) -> Dim

Computes the product of a range of the dimensions in the list.

If any in the range are dynamic, the result is a dynamic dimension value.

Parameters:

  • ​start (Int): The starting index.
  • ​end (Int): The end index.

Returns:

The product of all the dimensions.

contains​

contains[length: Int](self: Self, value: Dim) -> Bool

Determines whether the dimension list contains a specified dimension value.

Parameters:

  • ​length (Int): The number of elements in the list.

Args:

  • ​value (Dim): The value to find.

Returns:

True if the list contains a dimension of the specified value.

all_known​

all_known[length: Int](self: Self) -> Bool

Determines whether all dimensions are statically known.

Parameters:

  • ​length (Int): The number of elements in the list.

Returns:

True if all dimensions have a static value.

all_known[start: Int, end: Int](self: Self) -> Bool

Determines whether all dimensions within [start, end) are statically known.

Parameters:

  • ​start (Int): The first queried dimension.
  • ​end (Int): The last queried dimension.

Returns:

True if all queried dimensions have a static value.

create_unknown​

static create_unknown[length: Int]() -> Self

Creates a dimension list of all dynamic dimension values.

Parameters:

  • ​length (Int): The number of elements in the list.

Returns:

A list of all dynamic dimension values.

__str__​

__str__(self: Self) -> String

Converts the DimList to a String. The String is a comma separated list of the string representation of Dim.

Returns:

The string representation of the type.
