Trait Implementations

impl Clone for Event

fn clone(&self) -> Event

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Eq for Event

impl PartialEq<Event> for Event

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl Debug for Event

fn fmt(&self, fmt: &mut Formatter) -> Result<(), Error>

Formats the value using the given formatter.

impl Hash for Event

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given [Hasher].

fn hash_slice<H>(data: &[Self], state: &mut H) where     H: Hasher,

Feeds a slice of this type into the given [Hasher].

impl ExonumJson for Event

fn deserialize_field<B>(     value: &Value,     buffer: &mut B,     from: Offset,     to: Offset ) -> Result<(), Box<dyn Error>> where     B: WriteBufferWrapper,

write deserialized field in buffer on place.

fn serialize_field(&self) -> Result<Value, Box<dyn Error + Send + Sync>>

serialize field as json::Value

impl ExonumJsonDeserialize for Event

fn deserialize(value: &Value) -> Result<Self, Box<dyn Error>>

deserialize json value.

impl Serialize for Event

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error> where     S: Serializer,

Serialize this value into the given Serde serializer.

impl<'de> Deserialize<'de> for Event

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error> where     D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'a> Field<'a> for Event

unsafe fn read(buffer: &'a [u8], from: Offset, to: Offset) -> Self

Read Field from buffer, with given position, beware of memory unsafety, you should check Field before read.

fn write(&self, buffer: &mut Vec<u8>, from: Offset, to: Offset)

Write Field to buffer, in given position write doesn't lead to memory unsafety.

fn check(     buffer: &'a [u8],     from_st_val: CheckedOffset,     to_st_val: CheckedOffset,     latest_segment: CheckedOffset ) -> Result

Checks if data in the buffer could be deserialized. Returns an index of latest data seen. Default implementation simply checks that the length of segment equals field size.

fn field_size() -> Offset

Field's header size.

impl CryptoHash for Event

fn hash(&self) -> Hash

Returns a hash of the value.

impl StorageValue for Event

fn into_bytes(self) -> Vec<u8>

Serialize a value into a vector of bytes.

fn from_bytes(v: Cow<[u8]>) -> Self

Deserialize a value from bytes.
