Enum Error

#[non_exhaustive]
pub enum Error {
    MissingField {
        target: &'static str,
        field: &'static str,
    },
    Env {
        var_name: String,
        source: EnvVarError,
    },
    Leaderboard(Error),
}

Custom error type used by this crate’s API.

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.

MissingField

Fields

target: &'static str

Type of value that was supposed to be built.

field: &'static str

Name of missing field.

Env

Error while getting the value of an environment variable.

Fields

var_name: String

Name of environment variable.

source: EnvVarError

Error that occurred while trying to get environment variable’s value.

Leaderboard(Error)

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 Error

fn from(source: Error) -> Self

Converts to this type from the input type.
