Enum ndarray::SliceInfoElem [−][src]
A slice (range with step), an index, or a new axis token.
See also the s![]
macro for a convenient way to create a
SliceInfo<[SliceInfoElem; n], Din, Dout>
.
Examples
SliceInfoElem::Index(a)
is the index a
. It can also be created with
SliceInfoElem::from(a)
. The Python equivalent is [a]
. The macro
equivalent is s![a]
.
SliceInfoElem::Slice { start: 0, end: None, step: 1 }
is the full range
of an axis. It can also be created with SliceInfoElem::from(..)
. The
Python equivalent is [:]
. The macro equivalent is s![..]
.
SliceInfoElem::Slice { start: a, end: Some(b), step: 2 }
is every second
element from a
until b
. It can also be created with
SliceInfoElem::from(Slice::from(a..b).step_by(2))
. The Python equivalent
is [a:b:2]
. The macro equivalent is s![a..b;2]
.
SliceInfoElem::Slice { start: a, end: None, step: -1 }
is every element,
from a
until the end, in reverse order. It can also be created with
SliceInfoElem::from(Slice::from(a..).step_by(-1))
. The Python equivalent
is [a::-1]
. The macro equivalent is s![a..;-1]
.
SliceInfoElem::NewAxis
is a new axis of length 1. It can also be created
with SliceInfoElem::from(NewAxis)
. The Python equivalent is
[np.newaxis]
. The macro equivalent is s![NewAxis]
.
Variants
A range with step size. end
is an exclusive index. Negative begin
or end
indexes are counted from the back of the axis. If end
is
None
, the slice extends to the end of the axis.
Index(isize)
A single index.
A new axis of length 1.
