Struct extendr_api::prelude::perm::PermRef
source · pub struct PermRef<'a, I>where
I: Index,{ /* private fields */ }Expand description
Immutable permutation matrix view.
Implementations§
source§impl<'a, I> PermRef<'a, I>where
I: Index,
impl<'a, I> PermRef<'a, I>where
I: Index,
sourcepub fn new_checked(forward: &'a [I], inverse: &'a [I]) -> PermRef<'a, I>
pub fn new_checked(forward: &'a [I], inverse: &'a [I]) -> PermRef<'a, I>
Creates a new permutation, by checking the validity of the inputs.
§Panics
The function panics if any of the following conditions are violated:
forward and inverse must have the same length which must be less than or equal to
I::Signed::MAX, be valid permutations, and be inverse permutations of each other.
sourcepub unsafe fn new_unchecked(
forward: &'a [I],
inverse: &'a [I],
) -> PermRef<'a, I>
pub unsafe fn new_unchecked( forward: &'a [I], inverse: &'a [I], ) -> PermRef<'a, I>
Creates a new permutation reference, without checking the validity of the inputs.
§Safety
forward and inverse must have the same length which must be less than or equal to
I::Signed::MAX, be valid permutations, and be inverse permutations of each other.
sourcepub fn canonicalized(self) -> PermRef<'a, <I as Index>::FixedWidth>
pub fn canonicalized(self) -> PermRef<'a, <I as Index>::FixedWidth>
Cast the permutation to the fixed width index type.
sourcepub fn uncanonicalized<J>(self) -> PermRef<'a, J>where
J: Index,
pub fn uncanonicalized<J>(self) -> PermRef<'a, J>where
J: Index,
Cast the permutation from the fixed width index type.
