Expand description

A mutable view into a vector, supporting in-place operations and modifications.

This trait represents a temporary mutable reference to a vector’s data, allowing in-place arithmetic operations (+=, -=, *=) and other modifications. Mutable views can be created via the as_view_mut() method on a Vector.

Required Associated Types§

Source

type Owned

Source

type View

Source

type Index: VectorIndex

Required Methods§

Source

fn copy_from(&mut self, other: &Self::Owned)

Copy values from an owned vector into this view.

Source

fn copy_from_view(&mut self, other: &Self::View)

Copy values from another vector view into this view.

Source

fn axpy(&mut self, alpha: Self::T, x: &Self::Owned, beta: Self::T)

Compute the AXPY operation: self = alpha * x + beta * self

Source

fn set_index(&mut self, index: IndexType, value: Self::T)

Set the value at the specified index. Panics unless nbatch == 1; to write the same value into every batch use Self::fill_index.

Source

fn fill_index(&mut self, index: IndexType, value: Self::T)

Set the value at the specified index in every batch.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
