Struct Event

pub struct Event { /* private fields */ }

The Event struct represents a log event.

It is a collection of key-value pairs where the key is a string and the value is a string, number, or boolean The value may also be None to represent a null value.

Implementations

impl Event

pub fn new() -> Self

Create a new empty event

pub fn insert<T, S>(&mut self, key: S, value: T)

where S: Into<String> + Hash + Eq, T: Into<EventValue>,

Insert a key-value pair into the event. If the key already exists, the value will be replaced.

Example

use sigma_rust::Event;
let mut event = Event::new();
event.insert("name", "John Doe");
event.insert("age", 43);
event.insert("is_admin", true);
event.insert("null_value", None);

pub fn iter(&self) -> impl Iterator<Item = (&String, &EventValue)>

Iterate over the key-value pairs in the event

pub fn get(&self, key: &str) -> Option<&EventValue>

Get the value for a key in the event

pub fn values(&self) -> impl Iterator<Item = &EventValue>

Trait Implementations

impl Debug for Event

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

Formats the value using the given formatter.

impl Default for Event

fn default() -> Event

Returns the “default value” for a type.

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<T, S, const N: usize> From<[(S, T); N]> for Event

where S: Into<String> + Hash + Eq, T: Into<EventValue>,

fn from(values: [(S, T); N]) -> Self

Converts to this type from the input type.

impl TryFrom<Value> for Event

type Error = JSONError

The type returned in the event of a conversion error.

fn try_from(data: Value) -> Result<Self, Self::Error>

Performs the conversion.
