Struct vector::event::discriminant::Discriminant

pub struct Discriminant { /* private fields */ }

An event discriminant identifies a distinguishable subset of events. Intended for dissecting streams of events to sub-streams, for instance to be able to allocate a buffer per sub-stream. Implements PartialEq, Eq and Hash to enable use as a HashMap key.

Implementations

impl Discriminant

pub fn from_log_event( event: &LogEvent, discriminant_fields: &[impl AsRef<str>], ) -> Discriminant

Create a new Discriminant from the LogEvent and an ordered slice of fields to include into a discriminant value.

Trait Implementations

impl Clone for Discriminant

fn clone(&self) -> Discriminant

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Discriminant

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

Formats the value using the given formatter.

impl Hash for Discriminant

fn hash<H>(&self, state: &mut H)

where H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Discriminant

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

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

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Eq for Discriminant
