Enum ConfigError 

#[non_exhaustive]
pub enum ConfigError {
    InvalidEnvironment(String),
    InvalidValue {
        var: String,
        reason: String,
    },
    MissingEnvVar(String),
    MissingField(String),
}

Configuration error types.

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.

InvalidEnvironment(String)

The environment string could not be parsed.

InvalidValue

A configuration value was present but invalid.

Fields

var: String

The variable or field name.

reason: String

Why the value was rejected.

MissingEnvVar(String)

A required environment variable was not set.

MissingField(String)

A required builder field was not provided.

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.
