    },
    TooLarge,
    ReservedName {
        name: String,
    },
}

An error from instrument.

Variants

Parse

The source text does not parse.

Fields

messages: Vec<String>

The parser messages.

TooLarge

The source text or the instrumented text is larger than u32::MAX bytes.

ReservedName

The source declares a binding with a name that the prelude uses. See RESERVED_PREFIX.

Fields

name: String

Trait Implementations

impl Clone for MutationError

fn clone(&self) -> MutationError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MutationError

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

Formats the value using the given formatter.

impl Display for MutationError

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

Formats the value using the given formatter.

impl Eq for MutationError

impl Error for MutationError

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 PartialEq for MutationError

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

Equality operator ==.

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

Inequality operator !=.
