Enum StreamMemory 

pub enum StreamMemory {
    NoMemory,
    Static(StreamBuffer),
    Dynamic {
        buffer: StreamBuffer,
        has_spawn: bool,
        has_close: bool,
    },
    Instances {
        buffer: StreamBuffer,
        parameter: Vec<Parameter>,
    },
}

The kind of a stream’s memory

Variants

NoMemory

No memory is needed for this stream

Static(StreamBuffer)

Memory is needed, but only for a single instance living for the whole runtime

Dynamic

Memory is needed for a single instance that dynamically spawns and closes

Fields

buffer: StreamBuffer

The buffer of the memory

has_spawn: bool

Whether this stream is dynamically spawned

has_close: bool

Whether this stream is dynamically closed

Instances

Memory is required for a stream spawning multiple instances

Fields

buffer: StreamBuffer

The buffer of each stream’s instance

parameter: Vec<Parameter>

The parameter of the stream

Implementations

impl StreamMemory

pub fn parameters(&self) -> Option<&[Parameter]>

Returns the parameters of a stream if it is parameterized (or None otherwise)

pub fn num_parameters(&self) -> usize

Returns the number of parameters of a parameterized streams or 0 for unparameterized streams

impl StreamMemory

pub fn buffer(&self) -> Option<&StreamBuffer>

Returns the [Streambuffer] of the memory. Returns None if no memory is required

Trait Implementations

impl Add for StreamMemory

type Output = StreamMemory

The resulting type after applying the + operator.

fn add(self, rhs: Self) -> Self::Output

Performs the + operation.

impl Clone for StreamMemory

fn clone(&self) -> StreamMemory

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StreamMemory

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

Formats the value using the given formatter.

impl Hash for StreamMemory

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for StreamMemory

fn eq(&self, other: &StreamMemory) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
