Struct actyxos_sdk::event::Payload

pub struct Payload(_);

Compact binary storage of events created when they are received from the Event Service

see Event::extract for supported ways of using the data

Implementations

impl Payload

pub fn from_json_str(s: &str) -> Result<Payload, String>

pub fn compact<T: Serialize>(t: &T) -> Result<Payload, Error>

Construct a new Payload from the supplied serializable value.

pub fn extract<'a, T: Deserialize<'a>>(&'a self) -> Result<T, Error>

Try to lift the desired type from this Payload’s bytes.

pub fn json_value(&self) -> Value

Transform into a generic JSON structure that you can then traverse or query.

pub fn json_string(&self) -> String

Printable representation of this stored object as JSON — the stored Payload bytes are encoded in the CBOR binary format.

pub fn empty() -> Payload

Construct a Payload consisting only of the null value.

pub fn rough_size(&self) -> usize

Rough estimate of the in memory size of the contained opaque value

pub fn from_json_value(v: Value) -> Result<Payload, String>

Only to be used from tests, since it has bad performance due to a serde bug/issue

Trait Implementations

impl Abomonation for Payload

unsafe fn entomb<W: Write>(&self, _write: &mut W) -> Result<()>

Write any additional information about &self beyond its binary representation.

fn extent(&self) -> usize

Reports the number of further bytes required to entomb self.

unsafe fn exhume<'a, 'b>(
    &'a mut self,
    bytes: &'b mut [u8]
) -> Option<&'b mut [u8]>

Recover any information for &mut self not evident from its binary representation.

impl Clone for Payload

fn clone(&self) -> Payload

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Payload

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

Formats the value using the given formatter.

impl Default for Payload

fn default() -> Self

Returns the "default value" for a type.

impl<'de> Deserialize<'de> for Payload

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

Deserialize this value from the given Serde deserializer.

impl Eq for Payload

impl Ord for Payload

fn cmp(&self, other: &Payload) -> Ordering

This method returns an [Ordering] between self and other.

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl PartialEq<Payload> for Payload

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

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

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

This method tests for !=.

impl PartialOrd<Payload> for Payload

fn partial_cmp(&self, other: &Payload) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Payload) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Payload) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Payload) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Payload) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for Payload

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

Serialize this value into the given Serde serializer.
