Enum EventValue 

pub enum EventValue<'a> {
    Str(Cow<'a, str>),
    Int(i64),
    Float(f64),
    Bool(bool),
    Null,
    Array(Vec<EventValue<'a>>),
    Map(Vec<(Cow<'a, str>, EventValue<'a>)>),
}

A value retrieved from an event field.

Supports zero-copy borrows from JSON-backed events (Cow::Borrowed) and owned values from non-JSON sources (Cow::Owned). Null is distinct from field-absent (get_field returns None).

Variants

Str(Cow<'a, str>)

Int(i64)

Float(f64)

Bool(bool)

Null

Array(Vec<EventValue<'a>>)

Map(Vec<(Cow<'a, str>, EventValue<'a>)>)

Implementations

impl<'a> EventValue<'a>

pub fn as_str(&self) -> Option<Cow<'_, str>>

Coerce to string. Str as-is, Int/Float decimal, Bool “true”/“false”.

pub fn as_f64(&self) -> Option<f64>

Coerce to f64. Int lossless, Float as-is, Str parsed.

pub fn as_i64(&self) -> Option<i64>

Coerce to i64. Int as-is, Float truncated if exact, Str parsed.

pub fn as_bool(&self) -> Option<bool>

Coerce to bool. Bool as-is, Str: true/false/1/0/yes/no.

pub fn is_null(&self) -> bool

pub fn to_json(&self) -> Value

Convert to serde_json::Value.

Trait Implementations

impl<'a> Clone for EventValue<'a>

fn clone(&self) -> EventValue<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for EventValue<'a>

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

Formats the value using the given formatter.

impl<'a> From<&'a Value> for EventValue<'a>

fn from(v: &'a Value) -> Self

Converts to this type from the input type.

impl<'a> PartialEq for EventValue<'a>

fn eq(&self, other: &EventValue<'a>) -> 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.
