Enum ConfigError

#[non_exhaustive]
pub enum ConfigError {
    FormatJson {
        path: PathBuf,
        error: Error,
    },
    UnsupportedFormat(String),
    DisabledFormat {
        extension: String,
        feature: String,
    },
    Io {
        path: PathBuf,
        error: Error,
    },
}

Represents all the errors that can happen while reading the config.

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.

FormatJson

Failed to parse from JSON.

Fields

path: PathBuf

The path that failed to parse into JSON.

error: Error

The parsing serde_json::Error.

UnsupportedFormat(String)

Unknown config file name encountered.

DisabledFormat

Known file extension encountered, but corresponding parser is not enabled (cargo features).

Fields

extension: String

The extension encountered.

feature: String

The cargo feature to enable it.

Io

A generic IO error with context of what caused it.

Fields

path: PathBuf

The path the IO error occurred on.

error: Error

The std::io::Error.

Trait Implementations

impl Debug for ConfigError

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

Formats the value using the given formatter.

impl Display for ConfigError

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

Formats the value using the given formatter.

impl Error for ConfigError

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.
