Enum GlobalError

#[non_exhaustive]
pub enum GlobalError {
    ImmutableWrite,
    TypeMismatch,
}

An error that may occur upon operating on global variables.

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.

ImmutableWrite

Occurs when trying to write to an immutable global variable.

TypeMismatch

Occurs when trying writing a value with mismatching type to a global variable.

Trait Implementations

impl Debug for GlobalError

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

Formats the value using the given formatter.

impl Display for GlobalError

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

Formats the value using the given formatter.

impl Error for GlobalError

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>)
