Struct Buffer 

pub struct Buffer { /* private fields */ }

A Buffer holding HackRF transfer data.

Samples can be directly accessed as slices, and can be extended up to the length of the fixed-size underlying buffer.

When dropped, this buffer returns to the internal buffer pool it came from. It can either be backed by an allocation from the system allocator, or by some platform-specific way of allocating memory for zero-copy USB transfers.

Implementations

impl Buffer

pub fn capacity(&self) -> usize

Get how many samples this buffer can hold.

pub fn clear(&mut self)

Clear out the buffer’s samples.

pub fn len(&self) -> usize

Size of the buffer, in samples.

pub fn is_empty(&self) -> bool

Returns true if there are no samples in the buffer.

pub fn remaining_capacity(&self) -> usize

Remaining capacity in the buffer, in samples.

pub fn extend_zeros(&mut self, len: usize) -> &mut [ComplexI8]

Extend the buffer with some number of samples set to 0, and get a mutable slice to the newly initialized samples.

Panics

• If there is not enough space left for the added samples.

pub fn extend_from_slice(&mut self, slice: &[ComplexI8])

Extend the buffer with a slice of samples.

Panics

• If there is no space left in the buffer for the slice.

pub fn push(&mut self, val: ComplexI8)

Push a value onto the buffer.

Panics

• If there is no space left in the buffer.

pub fn bytes(&self) -> &[u8]

Get the sample sequence as a slice of bytes instead of complex values.

pub fn bytes_mut(&mut self) -> &mut [u8]

Get the sample sequence as a mutable slice of bytes instead of complex values.

pub fn samples(&self) -> &[ComplexI8]

Get the samples in the buffer.

pub fn samples_mut(&mut self) -> &mut [ComplexI8]

Mutably get the samples in the buffer.

Trait Implementations

impl Drop for Buffer

fn drop(&mut self)

Executes the destructor for this type.
