Struct ShapeConstraints 

pub struct ShapeConstraints {
    pub dimensions: Vec<Option<usize>>,
    pub min_elements: Option<usize>,
    pub max_elements: Option<usize>,
    pub require_square: bool,
    pub allow_broadcasting: bool,
}

Shape constraints for arrays and matrices

Fields

dimensions: Vec<Option<usize>>

Exact dimensions required (None = any size for that dimension)

min_elements: Option<usize>

Minimum number of elements

max_elements: Option<usize>

Maximum number of elements

require_square: bool

Whether matrix must be square (for 2D only)

allow_broadcasting: bool

Whether to allow broadcasting-compatible shapes

Implementations

impl ShapeConstraints

pub fn new() -> Self

Create new shape constraints

pub fn with_dimensions(self, dimensions: Vec<Option<usize>>) -> Self

Set exact dimensions

pub fn with_element_range(self, min: usize, max: usize) -> Self

Set element count range

pub fn require_square(self) -> Self

Require square matrix

pub fn allow_broadcasting(self) -> Self

Allow broadcasting

Trait Implementations

impl Clone for ShapeConstraints

fn clone(&self) -> ShapeConstraints

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ShapeConstraints

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

Formats the value using the given formatter.

impl Default for ShapeConstraints

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ShapeConstraints

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for ShapeConstraints

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 ShapeConstraints

fn eq(&self, other: &ShapeConstraints) -> 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 Serialize for ShapeConstraints

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
