Struct CustomSerialized

pub struct CustomSerialized { /* private fields */ }

A constant value stored as a serialized blob that can report its own type.

Implementations

impl CustomSerialized

pub fn new(typ: impl Into<Type>, value: Value) -> Self

Creates a new CustomSerialized.

pub fn value(&self) -> &Value

Returns the inner value.

pub fn try_from_custom_const_ref( cc: &impl CustomConst, ) -> Result<Self, SerializeError>

If cc is a Self, returns a clone of cc coerced to Self. Otherwise, returns a Self with cc serialized in it’s value.

pub fn try_from_dyn_custom_const( cc: &dyn CustomConst, ) -> Result<Self, SerializeError>

If cc is a Self, returns a clone of cc coerced to Self. Otherwise, returns a Self with cc serialized in it’s value.

pub fn try_from_custom_const( cc: impl CustomConst, ) -> Result<Self, SerializeError>

If cc is a Self, return cc coerced to Self. Otherwise, returns a Self with cc serialized in it’s value. Never clones cc outside of error paths.

pub fn try_from_custom_const_box( cc: Box<dyn CustomConst>, ) -> Result<Self, SerializeError>

If cc is a Self, return cc coerced to Self. Otherwise, returns a Self with cc serialized in it’s value. Never clones cc outside of error paths.

pub fn into_custom_const_box(self) -> Box<dyn CustomConst>

Attempts to deserialize the value in self into a Box<dyn CustomConst>. This can fail, in particular when the impl CustomConst for the trait is not linked into the running executable. If deserialization fails, returns self in a box.

Note that if the inner value is a Self we do not recursively deserialize it.

pub fn try_into_custom_const<CC: CustomConst>( self, ) -> Result<CC, DeserializeError>

Attempts to deserialize the value in self into a CC. Propagates failure.

Note that if the inner value is a Self we do not recursively deserialize it. In particular if that inner value were a Self whose inner value were a CC, then we would still fail.

Trait Implementations

impl Clone for CustomSerialized

fn clone(&self) -> CustomSerialized

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl CustomConst for CustomSerialized

fn name(&self) -> ValueName

An identifier for the constant.

fn equal_consts(&self, other: &dyn CustomConst) -> bool

Compare two constants for equality, using downcasting and comparing the definitions.

fn update_extensions( &mut self, extensions: &WeakExtensionRegistry, ) -> Result<(), ExtensionResolutionError>

Update the extensions associated with the internal values.

fn get_type(&self) -> Type

Report the type.

fn validate(&self) -> Result<(), CustomCheckFailure>

Check the value.

impl Debug for CustomSerialized

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CustomSerialized

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for CustomSerialized

fn eq(&self, other: &CustomSerialized) -> 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.

impl Serialize for CustomSerialized

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryHash for CustomSerialized

fn try_hash(&self, st: &mut dyn Hasher) -> bool

Hashes the value, if possible; else return false without mutating the Hasher. This relates with CustomConst::equal_consts just like Hash with Eq:
