Enum PathError 

pub enum PathError {
    MissingEquals,
    EmptyPath,
    EmptySegment {
        path: String,
    },
    BadIndex {
        path: String,
    },
    IndexInKeyPath {
        path: String,
    },
}

Why a path expression was rejected.

Carries the path text and nothing else — no --set, no --interpolate, no filenames. Provenance is the caller’s job.

IndexInKeyPath is raised by RefPath::try_into_keys alone, never by parsing. MissingEquals has no producer in this module — a bare RefPath has no = to miss. It belongs to PathLeaf, which parses key.path=value over this grammar and shares this error rather than wrapping it, so one spelling of a bad path reads the same wherever it was typed.

Variants

MissingEquals

No = in a key.path=value expression.

EmptyPath

The path is empty (=1, an empty ${...} body, an empty vec).

EmptySegment

A path segment is empty (a..b, .a, a.).

Fields

path: String

The path that contained an empty segment.

BadIndex

A bracket step is malformed: empty, not a number, too big, or unclosed.

Fields

path: String

The path that contained the bad bracket.

IndexInKeyPath

A path that arrived at a writer contained an array index.

Raised by RefPath::try_into_keys only, never by parsing: writers take keys one per segment because arrays replace wholesale on the merge side, so there is no meaning to writing element n.

Fields

path: String

The full path, rendered.

impl Eq for PathError

impl Error for PathError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for PathError

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
