Struct faer_core::ColRef

pub struct ColRef<'a, T> { /* private fields */ }

Column vector view with general row stride.

For usage examples, see MatRef.

Implementations

impl<'a, T> ColRef<'a, T>

pub unsafe fn from_raw_parts( ptr: *const T, nrows: usize, row_stride: isize ) -> Self

Returns a column vector slice from the given arguments.
ptr: pointer to the first element of the column vector.
ncols: number of columns of the column vector.
col_stride: offset between the first elements of two successive columns in the column vector.

Safety

ptr must be non null and properly aligned for type T.
For each i < nrows,
ptr.offset(i as isize * row_stride) must point to a valid initialized object of type T, unless memory pointing to that address is never read.
The referenced memory must not be mutated during the lifetime 'a.

pub fn as_ptr(self) -> *const T

Returns a pointer to the first (top) element of the column vector.

pub fn nrows(&self) -> usize

Returns the number of rows of the column vector.

pub fn ncols(&self) -> usize

Returns the number of columns of the column vector. Always returns 1.

pub fn row_stride(&self) -> isize

Returns the offset between the first elements of two successive rows in the column vector.

pub fn ptr_at(self, i: usize) -> *const T

Returns a pointer to the element at position (i, 0) in the column vector.

pub unsafe fn ptr_in_bounds_at_unchecked(self, i: usize) -> *const T

Returns a pointer to the element at position (i, 0) in the column vector, assuming it falls within its bounds with no bound checks.

Safety

Requires that

• i < self.nrows().

Otherwise, the behavior is undefined.

pub fn ptr_in_bounds_at(self, i: usize) -> *const T

Returns a pointer to the element at position (i, 0) in the column vector, while asserting that it falls within its bounds.

Panics

Requires that

• i < self.nrows().

Otherwise, it panics.

pub unsafe fn split_at_unchecked(self, i: usize) -> (Self, Self)

Splits the column vector into two parts in the following order: top, bottom.

Safety

Requires that

• i <= self.nrows().

Otherwise, the behavior is undefined.

pub fn split_at(self, i: usize) -> (Self, Self)

Splits the column vector into two parts in the following order: top, bottom.

Panics

Requires that

• i <= self.nrows().

Otherwise, it panics.

pub unsafe fn get_unchecked(self, i: usize) -> &'a T

Returns a reference to the element at position (i, 0), with no bound checks.

Safety

Requires i < self.nrows().

Otherwise, the behavior is undefined.

pub fn get(self, i: usize) -> &'a T

Returns a reference to the element at position (i, 0), or panics if the index is out of bounds.

pub fn as_2d(self) -> MatRef<'a, T>

Returns an equivalent matrix view over the same data.

pub fn transpose(self) -> RowRef<'a, T>

Returns the transpose of self.

pub unsafe fn subrows_unchecked(self, i: usize, nrows: usize) -> Self

Returns a view over subrows of self, starting at position i with a row count of nrows.

Safety

Requires that

• i <= self.nrows(),
• nrows <= self.nrows() - i.

Otherwise, the behavior is undefined.

pub fn subrows(self, i: usize, nrows: usize) -> Self

Returns a view over subrows of self, starting at position i with a row count of nrows.

Panics

Requires that

• i <= self.nrows(),
• nrows <= self.nrows() - i.

Otherwise, it panics.

pub fn cwise(self) -> ZipCol<(Self,)>

Returns a thin wrapper that can be used to execute coefficientwise operations on matrices.
