Enum HoconError 

#[non_exhaustive]
pub enum HoconError {
    Parse(ParseError),
    Resolve(ResolveError),
    Io(Error),
}

Unified error type returned by top-level parse functions.

Wraps the three possible failure modes: syntax errors (ParseError), substitution resolution failures (ResolveError), and file I/O errors (std::io::Error).

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Parse(ParseError)

Syntax error during lexing or parsing.

Resolve(ResolveError)

Substitution resolution failure (missing key, cycle, etc.).

Io(Error)

File I/O error when reading the top-level config file.

Trait Implementations

impl Debug for HoconError

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

Formats the value using the given formatter.

impl Display for HoconError

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

Formats the value using the given formatter.

impl Error for HoconError

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 From<Error> for HoconError

fn from(e: Error) -> Self

Converts to this type from the input type.

impl From<ParseError> for HoconError

fn from(e: ParseError) -> Self

Converts to this type from the input type.

impl From<ResolveError> for HoconError

fn from(e: ResolveError) -> Self

Converts to this type from the input type.
