Enum ResolverError 

pub enum ResolverError {
    MissingField {
        label: String,
        detail: String,
    },
    InvalidShape {
        reason: String,
    },
    Other(String),
}

Errors a DesignationResolver can return.

Variants

MissingField

The resolver could not find a value for the requested designation label, e.g., because an expected arg field was missing.

Fields

label: String

detail: String

InvalidShape

The context was present but not in the shape the resolver needed (e.g., expected JSON object, got an array).

Fields

reason: String

Other(String)

Generic resolver failure for cases that don’t fit the above.

Trait Implementations

impl Debug for ResolverError

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

Formats the value using the given formatter.

impl Display for ResolverError

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

Formats the value using the given formatter.

impl Error for ResolverError

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 From<ResolverError> for EngineError

fn from(source: ResolverError) -> Self

Converts to this type from the input type.
