Represents errors that can occur while processing environment variables.

Variants

ParseEnvError

Error that occurs when an environment variable cannot be parsed.

var_name is the name of the environment variable. var_value is the value of the environment variable. source is the underlying error that caused this error.

Fields

var_name: String

var_value: String

source: BoxError

ParseDefaultError

Error that occurs when a default value cannot be parsed.

var_name is the name of the environment variable. var_value is the default value of the environment variable. source is the underlying error that caused this error.

Fields

var_name: String

var_value: String

source: BoxError

MissingEnvVar(String)

Error that occurs when an expected environment variable is missing.

The string is the name of the missing environment variable.

InvalidKeyFormat(String)

Error that occurs when an environment variable key has an invalid format.

The string is the invalid key.

InvalidVarFormat(String)

Error that occurs when an environment variable value has an invalid format.

The string is the invalid value.

Trait Implementations

impl Debug for EnvStructError

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

Formats the value using the given formatter.

impl Display for EnvStructError

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

Formats the value using the given formatter.

impl Error for EnvStructError

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.
