Struct MinPlus 

pub struct MinPlus;

⌊.+, the min-plus product of shortest-path problems, at i64, f32 and f64. Its minimum treats NaN as MaxPlus’s maximum does.

Trait Implementations

impl Default for MinPlus

fn default() -> MinPlus

Returns the “default value” for a type.

impl Inner<f32> for MinPlus

type Out = f32

The type of each result.

fn inner_into( &self, a: &[f32], b: &[f32], size: [usize; 3], out: &mut [<MinPlus as Inner<f32>>::Out], )

The m×n inner product of a, an m×k matrix, and b, a k×n matrix, both row-major, written row-major into out, which holds m×n items. size is [m, k, n]. Where k is 0, each result is the identity of f. An integer result that doesn’t fit its type panics, where checked_into gives false.

fn inner(&self, a: &[T], b: &[T], size: [usize; 3]) -> Vec<Self::Out>

inner_into’s results, as a new row-major matrix.

fn checked_into( &self, a: &[T], b: &[T], size: [usize; 3], out: &mut [Self::Out], ) -> bool

inner_into, or false where an integer result doesn’t fit its type, for callers that keep integers exact or report overflow. Where it gives true, out holds the exact results. Floats always give true.

fn inner_ops( &self, a: &[T], b: &[T], _: [Orientation; 2], _: [usize; 3], ) -> Vec<Self::Out>

where T: Copy,

inner of the matrices that a and b give in the orientations given, with size [m, k, n] for those matrices. A transposed a holds a k×m matrix, row-major, and gives its m×k transpose. This default copies a transposed operand into its orientation. Float and complex PlusTimes read it in place.

fn inner_mapped( &self, a: Mapped<'_, T>, b: Mapped<'_, T>, orientations: [Orientation; 2], size: [usize; 3], ) -> Vec<Self::Out>

where T: Element,

inner_mapped_into’s results, as a new row-major matrix.

fn inner_mapped_into( &self, a: Mapped<'_, T>, b: Mapped<'_, T>, _: [Orientation; 2], size: [usize; 3], out: &mut [Self::Out], )

where T: Element,

inner_into of operands whose items come through mappings, as Mapped describes. This default reads each operand whole and copies transposed operands into their orientations. Float and complex PlusTimes read an operand that isn’t held in order one block of its stored rows at a time and multiply each block as it’s read. Only one block of that operand then exists at once.

impl Inner<f64> for MinPlus

type Out = f64

The type of each result.

fn inner_into( &self, a: &[f64], b: &[f64], size: [usize; 3], out: &mut [<MinPlus as Inner<f64>>::Out], )

The m×n inner product of a, an m×k matrix, and b, a k×n matrix, both row-major, written row-major into out, which holds m×n items. size is [m, k, n]. Where k is 0, each result is the identity of f. An integer result that doesn’t fit its type panics, where checked_into gives false.

fn inner(&self, a: &[T], b: &[T], size: [usize; 3]) -> Vec<Self::Out>

inner_into’s results, as a new row-major matrix.

fn checked_into( &self, a: &[T], b: &[T], size: [usize; 3], out: &mut [Self::Out], ) -> bool

inner_into, or false where an integer result doesn’t fit its type, for callers that keep integers exact or report overflow. Where it gives true, out holds the exact results. Floats always give true.

fn inner_ops( &self, a: &[T], b: &[T], _: [Orientation; 2], _: [usize; 3], ) -> Vec<Self::Out>

fn inner_mapped( &self, a: Mapped<'_, T>, b: Mapped<'_, T>, orientations: [Orientation; 2], size: [usize; 3], ) -> Vec<Self::Out>

where T: Element,

inner_mapped_into’s results, as a new row-major matrix.

fn inner_mapped_into( &self, a: Mapped<'_, T>, b: Mapped<'_, T>, _: [Orientation; 2], size: [usize; 3], out: &mut [Self::Out], )

where T: Element,

inner_into of operands whose items come through mappings, as Mapped describes. This default reads each operand whole and copies transposed operands into their orientations. Float and complex PlusTimes read an operand that isn’t held in order one block of its stored rows at a time and multiply each block as it’s read. Only one block of that operand then exists at once.

type Out = i64

The type of each result.

fn inner_into(&self, a: &[i64], b: &[i64], size: [usize; 3], out: &mut [i64])

The m×n inner product of a, an m×k matrix, and b, a k×n matrix, both row-major, written row-major into out, which holds m×n items. size is [m, k, n]. Where k is 0, each result is the identity of f. An integer result that doesn’t fit its type panics, where checked_into gives false.
