Enum KeyValue 

pub enum KeyValue {
    Null,
    Bool(bool),
    Int(i64),
    TimestampMicros(i64),
    Text(String),
    Bytes(Vec<u8>),
}

One typed key component fed to RowKeyEncoder.

The supported type tags are deliberately lean — they cover the partition keys of spec section 12.2 (numeric, textual, timestamp). Extension rule (spec section 4.10): a new value kind is a new variant with a fresh tag byte appended at the end of the tag space; tags are never reused or reordered, because keys persist in tablet bounds.

Variants

Null

SQL NULL; sorts before every other value.

Bool(bool)

Boolean; false sorts before true.

Int(i64)

Signed 64-bit integer.

TimestampMicros(i64)

Microseconds since the Unix epoch (the time-range partition type).

Text(String)

UTF-8 text.

Bytes(Vec<u8>)

Opaque bytes.

Implementations

impl KeyValue

pub fn type_name(&self) -> &'static str
