Enum ConfigError 

pub enum ConfigError {
    NotFound(String),
    TypeMismatch {
        key: String,
        expected: &'static str,
        got: &'static str,
    },
    PathError(String),
    Io(String),
    Parse(String),
    Serialize(String),
}

Errors that can occur during configuration operations.

Variants

NotFound(String)

Key not found in configuration.

TypeMismatch

Type mismatch when accessing value.

Fields

key: String

The key that was accessed

expected: &'static str

Expected type

got: &'static str

Actual type

PathError(String)

Path-related error (missing home, invalid path).

Io(String)

IO error (file not found, permission denied).

Parse(String)

Parse error (invalid format).

Serialize(String)

Serialization error.

Trait Implementations

impl Clone for ConfigError

fn clone(&self) -> ConfigError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

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, f: &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.

impl PartialEq for ConfigError

fn eq(&self, other: &ConfigError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
