Struct UnknownKeyInfo 

pub struct UnknownKeyInfo {
    pub key: String,
    pub path: PathBuf,
    pub line: usize,
    pub source: Option<Arc<str>>,
}

A single unknown-key violation discovered during strict-mode validation.

Flat, pattern-match-free data carrier: no nested enums to unwrap. Produced during strict-mode validation and surfaced through ClapfigError::unknown_keys.

source holds the full file contents at the time of validation, shared cheaply across all infos from the same file. Renderers use it to draw source snippets; it is None when the source is not retained (e.g. after round-tripping through a non-data path).

Fields

key: String

Dotted key path that was not recognized by the config schema (e.g. "database.typo").

path: PathBuf

Path to the config file that contained the unknown key.

line: usize

1-indexed line number where the key was found, or 0 if the line could not be located (best-effort heuristic).

source: Option<Arc<str>>

Full contents of the config file, shared across all infos from the same file. Used by renderers for source snippets.

Implementations

impl UnknownKeyInfo

pub fn leaf(&self) -> &str

Returns the leaf segment of the dotted key (e.g. "typo" for "database.typo"). Used by renderers to highlight the offending token.

Trait Implementations

impl Clone for UnknownKeyInfo

fn clone(&self) -> UnknownKeyInfo

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UnknownKeyInfo

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

Formats the value using the given formatter.
