Enum EncodeError 

pub enum EncodeError {
    BadKey,
    DuplicateKey,
    NestingTooDeep,
    IntegerOutOfRange,
    TooManyElements,
    NonFiniteFloat,
}

Why encode refused a value: one variant for each way a Value can break macula 12’s decoding rule, so nothing is written that decode, or any other stack, would refuse to read.

Variants

BadKey

A map key that is neither text nor an integer.

DuplicateKey

Two keys of one map that are equal: the same text, or the same integer.

NestingTooDeep

Arrays and maps nested more than MAX_NESTING_DEPTH levels.

IntegerOutOfRange

An integer below -2^63 or above 2^63-1.

TooManyElements

A value that holds more than MAX_ELEMENTS items.

NonFiniteFloat

A float that is NaN or infinite.

Trait Implementations

impl Eq for EncodeError

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 PartialEq for EncodeError

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

Equality operator ==.

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

Inequality operator !=.
