Struct Channel 

pub struct Channel {
    pub name: String,
    pub unit: String,
    pub times: Vec<f64>,
    pub values: Vec<f64>,
}

A single named signal channel.

Fields

name: String

Human-readable name, e.g. "temperature".

unit: String

Physical unit string, e.g. "K" or "m/s".

times: Vec<f64>

Ordered time-stamp array (seconds).

values: Vec<f64>

Value array, same length as times.

Implementations

impl Channel

pub fn new(name: impl Into<String>, unit: impl Into<String>) -> Self

Create a new empty channel.

pub fn push(&mut self, time: f64, value: f64)

Push one sample.

pub fn len(&self) -> usize

Number of samples.

pub fn is_empty(&self) -> bool

Return true when there are no samples.

pub fn min_value(&self) -> f64

Minimum value over all samples, or NAN if empty.

pub fn max_value(&self) -> f64

Maximum value over all samples, or NAN if empty.

pub fn mean(&self) -> f64

Arithmetic mean of all values, or NAN if empty.

pub fn variance(&self) -> f64

Sample variance (population).

pub fn std_dev(&self) -> f64

Standard deviation (population).

pub fn interp_linear(&self, t: f64) -> f64

Linearly interpolate the value at arbitrary time t. Clamps to the boundary if t is out of range.

pub fn interp_cubic(&self, t: f64) -> f64

Cubic (Catmull-Rom) spline interpolation at time t.

Trait Implementations

impl Clone for Channel

fn clone(&self) -> Channel

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Channel

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
