Enum EnvSettingsError

pub enum EnvSettingsError {
    Convert(&'static str, String, &'static str),
    File(String, Error),
    NotExists(&'static str),
}

The error that may occurs during EnvSettings resolution

Variants

Convert(&'static str, String, &'static str)

File(String, Error)

Error raised when environment variables resolution from a file fails

NotExists(&'static str)

Error raised when an environment variable not exists

Trait Implementations

impl Debug for EnvSettingsError

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

Formats the value using the given formatter.

impl Display for EnvSettingsError

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

Formats the value using the given formatter.

impl Error for EnvSettingsError

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 #99301)

Provides type-based access to context intended for error reports.

impl PartialEq for EnvSettingsError

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

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

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

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