impl MatInstance

pub fn from_cols(components: Vec<Instance>) -> Self

Panics

• if the number of columns is not [2, 3, 4]
• if the columns don’t have the same number of rows
• if the number of rows is not [2, 3, 4]
• if the elements don’t have the same type
• if the type is not a scalar

pub fn r(&self) -> usize

The row count.

pub fn c(&self) -> usize

The column count.

pub fn col(&self, i: usize) -> Option<&Instance>

Get a column vector.

pub fn col_mut(&mut self, i: usize) -> Option<&mut Instance>

Get a column vector.

pub fn get(&self, col: usize, row: usize) -> Option<&Instance>

Get a component.

pub fn get_mut(&mut self, i: usize, j: usize) -> Option<&mut Instance>

Get a component.

pub fn iter_cols(&self) -> impl Iterator<Item = &Instance>

pub fn iter_cols_mut(&mut self) -> impl Iterator<Item = &mut Instance>

pub fn iter(&self) -> impl Iterator<Item = &Instance>

pub fn iter_mut(&mut self) -> impl Iterator<Item = &mut Instance>

Trait Implementations

impl Clone for MatInstance

fn clone(&self) -> MatInstance

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Convert for MatInstance

fn convert_to(&self, ty: &Type) -> Option<Self>

Convert an instance to another type, if a feasible conversion exists.

fn convert_inner_to(&self, ty: &Type) -> Option<Self>

Convert an instance by changing its inner type to another.

fn concretize(&self) -> Option<Self>

Convert an abstract instance to a concrete type.

impl Debug for MatInstance

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

Formats the value using the given formatter.

impl Display for MatInstance

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

Formats the value using the given formatter.

impl From<MatInstance> for Instance

fn from(value: MatInstance) -> Self

Converts to this type from the input type.

impl IntoIterator for MatInstance

type Item = Instance

The type of the elements being iterated over.

type IntoIter = <Vec<Instance> as IntoIterator>::IntoIter

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl PartialEq for MatInstance

fn eq(&self, other: &MatInstance) -> 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 Ty for MatInstance

fn ty(&self) -> Type

get the type of an instance.

fn inner_ty(&self) -> Type

get the inner type of an instance (not recursive).
