Trait Implementations

impl<'a> ExonumJson for &'a PublicKey

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

write deserialized field in buffer on place.

fn serialize_field(&self) -> Result<Value, Box<Error>>

serialize field as json::Value

impl ExonumJsonDeserialize for PublicKey

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

deserialize json value.

impl<'a> Field<'a> for &'a PublicKey

fn field_size() -> Offset

Field's header size

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

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(
    _: &'a [u8],
    from: CheckedOffset,
    to: CheckedOffset,
    latest_segment: CheckedOffset
) -> Result

Checks if data in the buffer could be deserialized. Returns an index of latest data seen.
