Struct ParseError 

pub struct ParseError {
    pub kind: &'static str,
    pub reason: &'static str,
    pub input: String,
}

A lexical form did not match the grammar its type requires.

The input field carries at most ParseError::MAX_ECHO characters of the offending text — enough to identify a malformed archetype id, not enough to leak a clinical note that reached a parser by mistake.

Fields

kind: &'static str

The openEHR type that rejected the input, spelled as the specification spells it: ARCHETYPE_ID, OBJECT_VERSION_ID, TERMINOLOGY_ID.

reason: &'static str

Why the grammar rejected it.

input: String

The rejected text, truncated to ParseError::MAX_ECHO characters.

Implementations

impl ParseError

pub const MAX_ECHO: usize = 96

The maximum number of characters of rejected input an error will repeat.

Sized to hold the longest identifier openEHR defines with room to spare — a fully specialised ARCHETYPE_ID runs to roughly 80 characters — and to be uselessly short for anything document-shaped.

pub fn new(kind: &'static str, reason: &'static str, input: &str) -> Self

Builds a parse error, truncating the echoed input on a character boundary.

use openehr::ParseError;

let e = ParseError::new("TERMINOLOGY_ID", "empty name", "");
assert_eq!(e.kind, "TERMINOLOGY_ID");

pub fn invariant(class: &'static str, invariant: &'static str) -> Self

Builds an error for a broken class invariant, echoing nothing.

Constructors use this rather than ParseError::new. The distinction is not stylistic: a rejected identifier is design-time vocabulary and safe to repeat, whereas the value that broke DV_TEXT’s invariant is the clinical text itself. Same error type, two entry points, and the one that could leak takes no value to leak.

use openehr::ParseError;

let e = ParseError::invariant("DV_QUANTITY", "Units_valid");
assert_eq!(e.input, "");
