Enum LoadError 

#[non_exhaustive]
pub enum LoadError {
    Io(Error),
    Env(VarError),
}

A possible error value while loading a Secret from a SecretLoader

Produced by the TryFrom<SecretLoader> implementation for SecretString

Examples

use std::convert::TryFrom;
use std::convert::TryInto;

use secrecy::SecretString;
use secret_loader::LoadError;
use secret_loader::SecretLoader;

let plain_cred = SecretLoader::new("insecurepassword");
let secret: SecretString = plain_cred.try_into().expect("Plaintext credentials always convert");

// Env var may be missing
let env_cred = SecretLoader::new("env:MISSING_KEY");
let env_error = SecretString::try_from(env_cred).expect_err("Env var is not set");
assert!(matches!(env_error, LoadError::Env(_)));

// File may not available
let file_cred = SecretLoader::new("file:/does/not/exist");
let file_error = SecretString::try_from(file_cred).expect_err("File is missing");
assert!(matches!(file_error, LoadError::Io(_)));

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.

Io(Error)

An IO error was encountered while attempting to read from a file

Env(VarError)

A VarError was encountered while attempting to read from the environment

Trait Implementations

impl Debug for LoadError

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

Formats the value using the given formatter.

impl Display for LoadError

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

Formats the value using the given formatter.

impl Error for LoadError

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 From<Error> for LoadError

fn from(e: IoError) -> Self

Converts to this type from the input type.

impl From<VarError> for LoadError

fn from(e: VarError) -> Self

Converts to this type from the input type.
