Enum SerializerError 

pub enum SerializerError {
    Custom(String),
    CannotSerializeFloats,
    MapKeyMustBeStringlike,
}

An error that can occur when attempting to serialize a type into a Value.

Variants

Custom(String)

Some custom error string.

CannotSerializeFloats

SCALE does not support floating point values, and so we’ll hit this error if we try to encode any floats.

MapKeyMustBeStringlike

SCALE encoding is only designed to map from statically known structs to bytes. We use field names to figure out this mapping between named composite types and structs, so we don’t support encoding maps with non-string keys into Values.

Trait Implementations

impl Clone for SerializerError

fn clone(&self) -> SerializerError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SerializerError

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

Formats the value using the given formatter.

impl Display for SerializerError

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

Formats the value using the given formatter.

impl Error for SerializerError

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 Error for SerializerError

fn custom<T>(msg: T) -> Self

where T: Display,

Used when a Serialize implementation encounters any error while serializing a type.

impl PartialEq for SerializerError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
