Enum Error 

pub enum Error {
    Source(Vec<Diagnostic>),
    Pack(Error),
    TooManyIds(usize),
    Invalid(String),
}

Why a side of a comparison could not be read.

Variants

Source(Vec<Diagnostic>)

The source tree did not load; its diagnostics, which include every reference that does not resolve.

Pack(Error)

The pack did not open, verify or read.

TooManyIds(usize)

The world has more IDs than the limit, which this holds.

Invalid(String)

A document that loaded could not be read again.

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.
