Struct BindingPath 

pub struct BindingPath {
    pub source: BindingSource,
    pub segments: Vec<PathSegment>,
}

Source path for a binding – parsed from “$task_id.field.path”

Combines a source (where data comes from) with optional property access segments for nested data traversal.

Examples

$step1           → Task("step1"), segments: []
$step1.name      → Task("step1"), segments: [Field("name")]
$data[0].name    → Task("data"), segments: [Index(0), Field("name")]
$context.files.x → Context("files.x"), segments: []
$inputs.locale   → Input("locale"), segments: []
$env.API_URL     → Env("API_URL"), segments: []

Fields

source: BindingSource

Where the data comes from

segments: Vec<PathSegment>

Property access segments after the source

Implementations

impl BindingPath

pub fn parse(input: &str) -> Result<BindingPath, BindingPathError>

Parse a binding path string like “$task_id.field[0].name”

Reserved namespaces: context, inputs, env Everything else is a task reference or loop variable.

Loop variables (from for_each as: item) are resolved by the caller providing a loop_vars hint set. Without that hint, ambiguous single-segment paths like $item are treated as Task references by default. Callers can use parse_with_loop_vars for disambiguation.

pub fn parse_with_loop_vars( input: &str, loop_vars: &[&str], ) -> Result<BindingPath, BindingPathError>

Parse with loop variable hints for disambiguation.

Any top-level identifier matching loop_vars becomes BindingSource::LoopVar.

pub fn task_id(&self) -> Option<&Arc<str>>

Extract the task ID if this is a Task source

pub fn is_task_ref(&self) -> bool

Returns true if this binding references a task output

Trait Implementations

impl Clone for BindingPath

fn clone(&self) -> BindingPath

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BindingPath

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

Formats the value using the given formatter.

impl Display for BindingPath

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

Formats the value using the given formatter.

impl Hash for BindingPath

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

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 BindingPath

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