Enum spinoso_env::Error

pub enum Error {
    Argument(ArgumentError),
    Invalid(InvalidError),
}

Sum type of all errors possibly returned from get, put, and to_map.

These APIs can return errors under several conditions:

• An environment variable name is not convertable to a platform string.
• An environment variable value is not convertable to a platform string.
• An environment variable name contains a NUL byte.
• An environment variable name contains an = byte.
• An environment variable value contains a NUL byte.

Ruby represents these error conditions with different exception types.

Variants

Argument(ArgumentError)

Error that indicates an argument parsing or value logic error occurred.

See ArgumentError.

Invalid(InvalidError)

Error that indicates the access to the underlying platform APIs failed.

This error type corresponds to the EINVAL syscall error.

See InvalidError.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a copy of the value.

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

Performs copy-assignment from source.

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, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for Error

impl Error for Error

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

pub fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

pub fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

pub fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl From<ArgumentError> for Error

fn from(err: ArgumentError) -> Self

Performs the conversion.

impl From<InvalidError> for Error

fn from(err: InvalidError) -> Self

Performs the conversion.

impl Hash for Error

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

pub fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given Hasher.

impl Ord for Error

fn cmp(&self, other: &Error) -> Ordering

This method returns an Ordering between self and other.

#[must_use]pub fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]pub fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]pub fn clamp(self, min: Self, max: Self) -> Self

Restrict a value to a certain interval.

impl PartialEq<Error> for Error

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl PartialOrd<Error> for Error

fn partial_cmp(&self, other: &Error) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Error) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Error) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Error) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Error) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
