Struct Payload 

pub struct Payload(/* private fields */);

Compact binary storage of events created when they are received

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

Implementations

impl Payload

pub fn from_slice(bytes: &[u8]) -> Self

pub fn as_slice(&self) -> &[u8]

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 cbor(&self) -> &Cbor

Access the native CBOR representation

pub fn null() -> 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

pub fn as_bytes(&self) -> &[u8]

pub fn from_bytes(bytes: &[u8]) -> Self

Trait Implementations

impl Clone for Payload

fn clone(&self) -> Payload

Returns a duplicate 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 Ord for Payload

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

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Payload

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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

impl ReadCbor for Payload

fn read_cbor_impl(cbor: &Cbor) -> Result<Self>

where Self: Sized,

fn fmt(f: &mut impl Write) -> Result

fn name() -> String

fn read_cbor(cbor: &Cbor) -> Result<Self, CodecError>

where Self: Sized,

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.

impl WriteCbor for Payload

fn write_cbor<W: Writer>(&self, w: W) -> W::Output
