Enum ComponentRole 

pub enum ComponentRole {
    Source,
    Processor,
    Sink,
    Filter,
    Router,
}

The role of a component within a pipeline topology.

Per consolidated review (Doc 10, C02-7, C04-4): ComponentRole is the canonical name, replacing NodeRole (Doc 02) and StageRole (Doc 04).

Examples

use torvyn_types::ComponentRole;

let role = ComponentRole::Processor;
assert_eq!(format!("{}", role), "Processor");

Variants

Source

Produces stream elements by pulling from an external data source.

Processor

Transforms stream elements (1:1 input-to-output mapping).

Sink

Consumes stream elements by writing to an external destination.

Filter

Evaluates whether elements pass a predicate (accept/reject, no new buffer).

Router

Routes elements to one or more named output ports.

Implementations

impl ComponentRole

pub const fn is_producer(&self) -> bool

Returns true if this role produces stream elements.

COLD PATH — called during topology validation.

pub const fn is_consumer(&self) -> bool

Returns true if this role consumes stream elements.

COLD PATH — called during topology validation.

Trait Implementations

impl Clone for ComponentRole

fn clone(&self) -> ComponentRole

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ComponentRole

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ComponentRole

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ComponentRole

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

Formats the value using the given formatter.

impl Hash for ComponentRole

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 ComponentRole

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

impl Serialize for ComponentRole

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
