Struct Error 

pub struct Error {
    pub kind: ErrorKind,
    pub path: Option<String>,
    pub source_location: Option<SourceLocation>,
    pub help: Option<String>,
    pub cause: Option<String>,
}

Main error type for holoconf operations

Fields

kind: ErrorKind

The kind of error that occurred

path: Option<String>

source_location: Option<SourceLocation>

Source location (file, line) if available

help: Option<String>

Actionable help message

cause: Option<String>

Underlying cause (as string for Clone compatibility)

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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.
