pub enum EnvParseError {
    InvalidUnicode(String),
    InvalidLevel(String),
    EmptyModule(String),
    DuplicateGlobalLevel(String),
}

DuplicateGlobalLevel(String)

Multiple bare level directives were found (e.g., debug,warn).

Trait Implementations

impl Clone for EnvParseError

fn clone(&self) -> EnvParseError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EnvParseError

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

Formats the value using the given formatter.

impl Display for EnvParseError

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

Formats the value using the given formatter.

impl Error for EnvParseError

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>)
