Trait ndarray::ScalarOperand [−][src]
pub trait ScalarOperand: 'static + Clone { }
Elements that can be used as direct operands in arithmetic with arrays.
For example, f64
is a ScalarOperand
which means that for an array a
,
arithmetic like a + 1.0
, and, a * 2.
, and a += 3.
are allowed.
In the description below, let A
be an array or array view,
let B
be an array with owned data,
and let C
be an array with mutable data.
ScalarOperand
determines for which scalars K
operations &A @ K
, and B @ K
,
and C @= K
are defined, as right hand side operands, for applicable
arithmetic operators (denoted @
).
Left hand side scalar operands are not related to this trait
(they need one impl
per concrete scalar type); but they are still
implemented for the same types, allowing operations
K @ &A
, and K @ B
for primitive numeric types K
.
This trait does not limit which elements can be stored in an array in general.
Non-ScalarOperand
types can still participate in arithmetic as array elements in
in array-array operations.
