Struct Parameters 

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

A named collection of Params bound to an operation’s declared inputs.

Callers build Parameters through the params! macro when adding a step or a return block. Draft-time validation uses Param::get_references to walk every contained parameter and check that all references resolve; at runtime, resolution turns each Param into a StoreEntry keyed by "{step_name}.{input_name}" in the runtime store.

Implementations

impl Parameters

pub fn new(map: HashMap<String, Param>) -> Self

Wraps a ready-built map of named parameters. Prefer the params! macro in user code.

pub fn get(&self, key: &str) -> Option<&Param>

Returns the parameter bound to the given input name, or None if the name is not bound.

pub fn keys(&self) -> impl Iterator<Item = &String>

Iterates over the bound input names.

pub fn values(&self) -> impl Iterator<Item = &Param>

Iterates over the bound Params.

pub fn iter(&self) -> impl Iterator<Item = (&String, &Param)>

Iterates over (input_name, param) pairs.

pub fn resolve_in_store( &self, prefix_part: impl Into<String>, store: &mut Store<StoreEntry>, ) -> Result<String, OperationError>

Resolves every parameter against store and writes each result back into the same store under "{prefix_part}.{input_name}". Returns the prefix for use by the caller.

pub fn resolve_to_store( &self, prefix_part: impl Into<String>, src: &Store<StoreEntry>, dst: &mut Store<StoreEntry>, ) -> Result<(), OperationError>

Resolves every parameter against src and writes each result into dst under "{prefix_part}.{input_name}". Used when the source and destination stores differ — for example, when resolving a return block’s parameters against the pipeline’s variables store and placing the results in a fresh returns store.

Trait Implementations

impl Clone for Parameters

fn clone(&self) -> Parameters

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Parameters

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

Formats the value using the given formatter.
