Enum EnumBufferState

pub enum EnumBufferState<I> {
    Constant(u32),
    Varying(TimedEnumValues<I>),
}

Represents the state of an enum value across a buffer

Here we refer to the enum by the index of the value, that is, the index of the value in the values array of the parameter.

Variants

Constant(u32)

The value is constant across the buffer.

Varying(TimedEnumValues<I>)

The value changes over the course of the buffer, represented by a TimedEnumValues.

Implementations

impl<I: IntoIterator<Item = TimedValue<u32>>> EnumBufferState<I>

pub fn value_at_start_of_buffer(self) -> u32

Get the value of the parameter at the start of the buffer, represented by the index of the value in the values array of the parameter.

Examples

assert_eq!(EnumBufferState::Varying(TimedEnumValues::new(
  vec![TimedValue { sample_offset: 0, value: 1 },
       TimedValue { sample_offset: 100, value: 2 }],
  128,
  0..3
).unwrap()).value_at_start_of_buffer(), 1);

Trait Implementations

impl<I: Clone> Clone for EnumBufferState<I>

fn clone(&self) -> EnumBufferState<I>

Returns a copy of the value.

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

Performs copy-assignment from source.
