Enum SettingsError 

#[non_exhaustive]
pub enum SettingsError {
    Deserialize {
        source: String,
        error: Error,
    },
    Io {
        path: String,
        error: Error,
    },
    Invalid(Box<dyn Error + Sync + Send>),
}

Error returned by settings construction. Aliases provcfg::Error, every failure surfaces from there (source deserialization or config-file I/O), so kellnr-side code keeps a domain-flavoured name without inventing its own opaque box. The error type returned by Config::build and the add_*_file helpers.

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.

Deserialize

A source’s raw data could not be deserialized into the target struct.

Fields

source: String

error: Error

Io

A config file could not be read from disk.

Fields

path: String

error: Error

Invalid(Box<dyn Error + Sync + Send>)

The config was built, but its validator rejected it, see LiveConfig::with_validator (live feature).

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

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.
