Struct Labels 

pub struct Labels(/* private fields */);

The labels of symbols, one row per stream: the index $a \in \{0, \dots, M - 1\}$ of every symbol of an alphabet of $M$ (a chirp of chirp spread spectrum, a level of continuous-phase modulation, a point of a constellation), the input and the decisions of the waveforms that carry an index (Modulate<Labels>).

Implementations

impl Labels

pub fn new(data: Array2<usize>) -> Labels

A container from a [n_streams, n] array.

pub fn zeros(n_streams: usize, n: usize) -> Labels

n_streams streams of n zeros.

pub fn from_stream(v: Vec<usize>) -> Result<Labels>

One stream.

Errors

Never in practice; the signature matches Self::from_streams.

pub fn from_streams(streams: &[Vec<usize>]) -> Result<Labels>

Several streams of equal length.

Errors

Error::Shape if the streams have different lengths.

pub fn n_streams(&self) -> usize

Number of streams.

pub fn len(&self) -> usize

Number of elements per stream.

pub fn is_empty(&self) -> bool

Whether the streams are empty.

pub fn stream(&self, i: usize) -> &[usize]

Stream i as a slice (the layout is always standard).

pub fn stream_view(&self, i: usize) -> ArrayView1<'_, usize>

Stream i as an ndarray view.

pub fn stream_view_mut(&mut self, i: usize) -> ArrayViewMut1<'_, usize>

Stream i as a mutable ndarray view.

pub fn as_slice(&self) -> &[usize]

All the elements, stream after stream.

pub fn set_stream(&mut self, x: &[usize])

Make self the single stream x, reusing its storage when the length is unchanged (ADR 0011).

pub fn assign(&mut self, a: &Array2<usize>)

Make self a copy of a, reusing its storage when the shape is unchanged (ADR 0011).

pub fn stream_mut(&mut self, i: usize) -> &mut [usize]

Stream i as a mutable slice.

pub fn as_slice_mut(&mut self) -> &mut [usize]

All the elements, stream after stream, mutable.

pub fn as_array(&self) -> &Array2<usize>

The underlying [n_streams, n] array.

pub fn as_array_mut(&mut self) -> &mut Array2<usize>

The underlying array, mutable.

pub fn resize(&mut self, n_streams: usize, n: usize)

Resize to n_streams × n (the content is reset when the shape changes), so that an _into method can reuse a caller-owned buffer.

Trait Implementations
