Struct ConfigError 

pub struct ConfigError {
    pub message: String,
    pub field: Option<String>,
    pub cause: Option<String>,
}

Error type for configuration operations.

Fields

message: String

Error message

field: Option<String>

Field that caused the error (if applicable)

cause: Option<String>

Underlying cause (if any)

Implementations

impl ConfigError

pub fn new(message: &str) -> Self

Create a new configuration error.

pub fn field_error(field: &str, message: &str) -> Self

Create an error for a specific field.

pub fn with_cause(self, cause: &str) -> Self

Add a cause to the 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.
