Struct StageId 

pub struct StageId(/* private fields */);

Identifier for a pipeline stage. Carried by crate::Error variants and by crate::StageFailure so a consumer can route or log by stage name.

Stages assigned through the builder default to descriptive names derived from the operation ("source", "map", "filter", "batch", "sink", …). Override with crate::PipelineBuilder::stage_id right before adding the stage.

Example

use pipe_io::StageId;

let id = StageId::new("ingest");
assert_eq!(id.as_str(), "ingest");
assert_eq!(format!("{id}"), "ingest");

Implementations

impl StageId

pub const fn new(name: &'static str) -> Self

Construct a stage identifier from a &'static str.

pub const fn as_str(&self) -> &'static str

Return the underlying &'static str.

Trait Implementations

impl Clone for StageId

fn clone(&self) -> StageId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StageId

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

Formats the value using the given formatter.

impl Display for StageId

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

Formats the value using the given formatter.

impl From<&'static str> for StageId

fn from(value: &'static str) -> Self

Converts to this type from the input type.

impl Hash for StageId

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 StageId

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