pub struct Apply<F, A, B> where
F: FnMut(&A) -> B + Send + 'static,
A: Send + 'static,
B: Send + 'static, { /* private fields */ }Expand description
Applies a function to each sample in the stream.
Inputs
in: Input
Outputs
out: Output after function applied
Usage
use futuresdr::blocks::Apply;
use futuresdr::runtime::Flowgraph;
use num_complex::Complex;
let mut fg = Flowgraph::new();
// Double each sample
let doubler = fg.add_block(Apply::new(|i: &f32| i * 2.0));
// Note that the closure can also hold state
let mut last_value = 0.0;
let moving_average = fg.add_block(Apply::new(move |i: &f32| {
let new_value = (last_value + i) / 2.0;
last_value = *i;
new_value
}));
// Additionally, the closure can change the type of the sample
let to_complex = fg.add_block(Apply::new(|i: &f32| {
Complex {
re: 0.0,
im: *i,
}
