Struct Pull 

pub struct Pull<N> { /* private fields */ }

A wrapper around a Node that enables pull evaluation across all inputs.

The implementation of Node will match the inner node type N, but with a unique implementation of Node::pull_eval.

Implementations

impl<N: Node> Pull<N>

pub fn all(node: N) -> Self

Given some node, return a Pull node enabling pull evaluation across all outputs.

pub fn new(node: N, conf: EvalConf) -> Self

Given some node, return a Pull node enabling pull evaluation across some subset of the outputs.

Trait Implementations

impl<N: CaHash> CaHash for Pull<N>

fn hash(&self, hasher: &mut Hasher)

Hash self to produce a stable content address.

impl<N: Clone> Clone for Pull<N>

fn clone(&self) -> Pull<N>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<N: Debug> Debug for Pull<N>

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

Formats the value using the given formatter.

impl<'de, N> Deserialize<'de> for Pull<N>

where N: Deserialize<'de>,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<N: Node> Node for Pull<N>

fn n_inputs(&self, ctx: MetaCtx<'_>) -> usize

The number of inputs to the node.

fn n_outputs(&self, ctx: MetaCtx<'_>) -> usize

The number of outputs from the node.

fn branches(&self, ctx: MetaCtx<'_>) -> Vec<EvalConf>

The list of possible branches from this node.

fn expr(&self, ctx: ExprCtx<'_, '_>) -> ExprResult

The expression that, given the expressions of connected inputs, produces the output(s).

fn push_eval(&self, ctx: MetaCtx<'_>) -> Vec<EvalConf>

Specifies whether or not code should be generated to allow for push evaluation from instances of this node. Enabling push evaluation allows applications to call into the graph by calling the resulting generated code at runtime.

fn pull_eval(&self, _ctx: MetaCtx<'_>) -> Vec<EvalConf>

Specifies whether or not code should be generated to allow for pull evaluation from instances of this node. Enabling pull evaluation allows applications to call into the graph by loading the resulting generated code at runtime.

fn inlet(&self, ctx: MetaCtx<'_>) -> bool

Whether or not this node acts as an inlet for some nested graph.

fn outlet(&self, ctx: MetaCtx<'_>) -> bool

Whether or not this node acts as an outlet for some nested graph.

fn stateful(&self, ctx: MetaCtx<'_>) -> bool

Whether or not the node requires access to state.

fn register(&self, ctx: RegCtx<'_, '_>)

Function for registering necessary types, functions and initialising any default values as necessary.

fn required_addrs(&self) -> Vec<ContentAddr>

Returns the content addresses of external nodes this node requires.

fn delay(&self, _ctx: MetaCtx<'_>) -> bool

Whether or not this node is a unit delay: its output is the value its input received on the previous evaluation.

fn visit(&self, _ctx: Ctx<'_, '_>, _visitor: &mut dyn Visitor)

Traverse all nested nodes, depth-first, with the given Visitor.

impl<N> Serialize for Pull<N>

where N: Serialize,

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
