Enum DependencyPattern 

pub enum DependencyPattern {
    SameFrame,
    Window {
        before: usize,
        after: usize,
    },
    FrameMap(DynamicDependencyBounds),
    Dynamic(DynamicDependencyBounds),
}

Declares which upstream frames a node may request while producing one output frame.

Variants

SameFrame

Input frame must equal output frame.

Window

Input frame may be in [output - before, output + after].

Fields

before: usize

Maximum number of frames allowed before output frame.

after: usize

Maximum number of frames allowed after output frame.

FrameMap(DynamicDependencyBounds)

Input frame is mapped by filter logic but must stay within declared bounds.

Dynamic(DynamicDependencyBounds)

Input frame is chosen at runtime but must stay within declared bounds.

Implementations

impl DependencyPattern

pub const fn same_frame() -> DependencyPattern

Creates same-frame dependency contract.

pub const fn window(before: usize, after: usize) -> DependencyPattern

Creates bounded window dependency contract.

pub const fn frame_map(bounds: DynamicDependencyBounds) -> DependencyPattern

Creates frame-map dependency contract.

pub const fn dynamic(bounds: DynamicDependencyBounds) -> DependencyPattern

Creates dynamic dependency contract.

pub const fn allows(&self, output: usize, requested: usize) -> bool

Returns true when requested frame is allowed for one output frame.

Trait Implementations

impl Clone for DependencyPattern

fn clone(&self) -> DependencyPattern

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DependencyPattern

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

Formats the value using the given formatter.

impl PartialEq for DependencyPattern

fn eq(&self, other: &DependencyPattern) -> 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.
