pub struct UnsetError<'a> {
    pub name: &'a str,
    pub read_only_location: &'a Location,
}

Error that occurs when unsetting a read-only variable

Fields

name: &'a str

Variable name.

read_only_location: &'a Location

Location where the existing variable was made read-only.

Trait Implementations

impl<'a> Clone for UnsetError<'a>

fn clone(&self) -> UnsetError<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for UnsetError<'a>

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

Formats the value using the given formatter.

impl<'a> Display for UnsetError<'a>

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

Formats the value using the given formatter.

impl<'a> Error for UnsetError<'a>

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<'a> PartialEq for UnsetError<'a>

fn eq(&self, other: &UnsetError<'a>) -> bool

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
