Struct Source 

pub struct Source<F, A, O = DefaultCpuWriter<A>>
where
    F: FnMut() -> A + Send + 'static,
    A: Send + 'static,
    O: CpuBufferWriter<Item = A>,
{ /* private fields */ }

Repeatedly apply a function to generate samples.

Stream Inputs

No stream inputs.

Stream Outputs

output: Generated output samples.

Usage

use futuresdr::blocks::Source;

// Generate zeroes
let source = Source::new(|| { 0.0f32 });

Implementations

impl<F, A, O> Source<F, A, O>

where F: FnMut() -> A + Send + 'static, A: Send + 'static, O: CpuBufferWriter<Item = A>,

pub fn output(&mut self) -> &mut O

Getter for stream port.

impl<F, A> Source<F, A, DefaultCpuWriter<A>>

where F: FnMut() -> A + Send + 'static, A: CpuSample,

pub fn new(f: F) -> Self

Create Source block with the default stream buffer.

impl<F, A, O> Source<F, A, O>

where F: FnMut() -> A + Send + 'static, A: Send + 'static, O: CpuBufferWriter<Item = A>,

pub fn with_buffer(f: F) -> Self

Create Source block with a custom stream buffer.
