Struct OwnedElementRef 

pub struct OwnedElementRef { /* private fields */ }

Owned runtime equivalent of ElementRef.

Used by DirectoryValidatorBuilder and DirectoryValidator::from_owned_definitions to construct validators from data that is not available at compile time (e.g. loaded from JSON or a database at startup).

Use OwnedElementRef::new for compile-time-known positions (panics on invalid input, no error handling noise) or OwnedElementRef::try_new when the position comes from an external source and you need a Result. Fields are private to prevent bypassing the position invariant through struct-literal syntax.

Implementations

impl OwnedElementRef

pub fn new( position: u8, data_element: String, status: Status, max_repeat: u8, ) -> Self

Construct an owned element reference.

This is the ergonomic constructor for compile-time-known positions. It panics immediately on invalid input so that call sites with literal position numbers require no .unwrap() / .expect() boilerplate.

Use try_new instead when the position originates from an external source (user input, config file, database) and you need a Result to propagate errors gracefully.

Panics

Panics if position is 0 (positions are one-based).

pub fn try_new( position: u8, data_element: String, status: Status, max_repeat: u8, ) -> Result<Self, EdifactError>

Construct an owned element reference, returning an error for position 0.

Prefer this over new when the position comes from an external source (user input, config file, database) and you want to handle the error without panicking.

Errors

Returns EdifactError::InvalidElementPosition if position is 0.

pub fn position(&self) -> u8

One-based element position (always >= 1).

pub fn data_element(&self) -> &str

UN/EDIFACT data element identifier.

pub fn status(&self) -> Status

Requirement status of this element.

pub fn max_repeat(&self) -> u8

Maximum repetition count for this element.
