Enum EncodeError 

pub enum EncodeError {
    WrongShape {
        kind: &'static str,
        expected: &'static str,
        got: String,
    },

    BadVariant,
}

An argument value whose shape does not match its declared ParamType, surfaced before the request is sent rather than as an opaque resolver error.

Variants

WrongShape

A value’s JSON kind didn’t match what the param type expects.

Fields

kind: &'static str

The ParamType kind being encoded (e.g. list, record).

expected: &'static str

The JSON shape that was required (e.g. array, object).

got: String

The JSON shape actually provided.

TupleArity

A tuple value had the wrong number of elements.

Fields

expected: usize

The declared tuple arity.

got: usize

The arity of the provided value.

MissingField(String)

A record value was missing a declared field.

UnknownField(String)

A record value carried a field the type does not declare.

UnknownCase(String)

A variant value named a case the type does not declare.

BadVariant

A variant value was not a single-key object naming its case.

Trait Implementations

impl Debug for EncodeError

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

Formats the value using the given formatter.

impl Display for EncodeError

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

Formats the value using the given formatter.

impl Error for EncodeError

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<EncodeError> for Error

fn from(source: EncodeError) -> Self

Converts to this type from the input type.
