Struct AnySnapshot

pub struct AnySnapshot(Value);

A type erased snapshot value. Or, alternatively, you can think of it as a partially (de)serialized value that can be nested in other values without incurring double encoding in the final output.

There is a performance and code size cost to this type, so only use it if really needed, for example, in traits that must be dyn compatible.

If the intermediate representation and the final serialization format don’t match, for example, if AnySnapshot was implemented with serde_json::Value but then written to a file as CBOR, it will technically work, but the result might not match what you’d get if you directly serialized the original value. That should be OK as long as the serialization and deserialization paths make symmetric use of AnySnapshot.

Implementations

impl AnySnapshot

pub fn to_any(x: impl Serialize) -> Result<Self>

pub fn from_any<T: DeserializeOwned>(x: Self) -> Result<T>

Trait Implementations

impl Clone for AnySnapshot

fn clone(&self) -> AnySnapshot

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AnySnapshot

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for AnySnapshot

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for AnySnapshot

fn eq(&self, other: &AnySnapshot) -> 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 AnySnapshot

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
