Struct FixedKeyRecord 

pub struct FixedKeyRecord<K, V> {
    pub key: K,
    pub value: V,
    pub timestamp: i64,
}

A record whose KEY is immutable. with_value changes the value (possibly the type), keeping the key and timestamp. Unlike Record, the key is not optional: a fixed-key processor is only reached for records that carry a key (a null-key record cannot have its key “preserved” — process_values requires a non-null key, matching the JVM).

Fields

key: K

value: V

timestamp: i64

Implementations

impl<K, V> FixedKeyRecord<K, V>

pub fn with_value<V2>(self, value: V2) -> FixedKeyRecord<K, V2>

Replace the value (and possibly its type), preserving key and timestamp.

Trait Implementations

impl<K: Clone, V: Clone> Clone for FixedKeyRecord<K, V>

fn clone(&self) -> FixedKeyRecord<K, V>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<K: Debug, V: Debug> Debug for FixedKeyRecord<K, V>

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

Formats the value using the given formatter.

impl<K: Eq, V: Eq> Eq for FixedKeyRecord<K, V>

impl<K: PartialEq, V: PartialEq> PartialEq for FixedKeyRecord<K, V>

fn eq(&self, other: &FixedKeyRecord<K, V>) -> 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.
