Struct Error

pub struct Error<E1, E2> {
    pub cause: ErrorCause<E1, E2>,
    pub location: Range<usize>,
}

Description of an error that occurred during expansion

Fields

cause: ErrorCause<E1, E2>

Cause of the error

location: Range<usize>

Range of the substring in the evaluated expression string where the error occurred

Trait Implementations

impl<E1: Clone, E2: Clone> Clone for Error<E1, E2>

fn clone(&self) -> Error<E1, E2>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<E1: Debug, E2: Debug> Debug for Error<E1, E2>

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

Formats the value using the given formatter.

impl<E1, E2> Display for Error<E1, E2>

where ErrorCause<E1, E2>: Display,

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

Formats the value using the given formatter.

impl<E1, E2> Error for Error<E1, E2>

where Self: Debug + Display,

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<E1: Hash, E2: Hash> Hash for Error<E1, E2>

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

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<E1: PartialEq, E2: PartialEq> PartialEq for Error<E1, E2>

fn eq(&self, other: &Error<E1, E2>) -> 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.
