Enum VectorizerValue 

Source
pub enum VectorizerValue {
    Null,
    Bool(bool),
    Int(i64),

Expand description

The wire value model (WIRE-002) — byte-compatible with the value models the family shipped before Thunder, by construction.

Map is an insertion-ordered pair list because keys may be any value.

Variants§

§

Null

SQL NULL / nil.

§

Bool(bool)

§

Int(i64)

§

Float(f64)

§

Bytes(Arc<[u8]>)

Raw bytes, refcounted. Emitted as MessagePack bin (WIRE-010); the legacy int-array form decodes too (WIRE-011).

The payload is Arc<[u8]> rather than Vec<u8> so a decoded value can move into a product’s store, and a stored buffer can reach the encoder, as a refcount bump instead of a memcpy — in both directions. With an owned Vec, a server paid one full copy of the payload per read and per write, worst exactly where a binary protocol is supposed to win: large values and the raw-LE-f32 embeddings this wire exists to carry.

The wire is unchanged. The emitted form is still MessagePack bin and the legacy int-array form is still accepted, so no corpus vector moves and no other language lane is affected — only the Rust type.

§

Str(String)

§

Array(Vec<Value>)

§

Map(Vec<(Value, Value)>)

Implementations§

Source§

impl Value

Source

pub fn as_str(&self) -> Option<&str>

Extract the inner string slice.

Source

pub fn as_bytes(&self) -> Option<&[u8]>

Extract bytes (also accepts Str as UTF-8 bytes).

Source

pub fn as_shared_bytes(&self) -> Option<&Arc<[u8]>>

The shared buffer behind Value::Bytes, for the zero-copy path.

Arc::clone on the result is a refcount bump: a product can put the decoded payload straight into its store without copying it.

Source

pub fn into_shared_bytes(self) -> Option<Arc<[u8]>>

Consume the value and take its shared buffer — no copy, no refcount bump beyond the move itself.

Source

pub fn bytes(buffer: impl Into<Arc<[u8]>>) -> Value

Build a Bytes value from anything that can become a shared buffer.

Source

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

Extract an integer.

Source

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

Extract a float (accepts Int widened to f64).

Source

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

Extract a bool.

Source

pub fn as_array(&self) -> Option<&[Value]>

Extract the array items.

Source

pub fn as_map(&self) -> Option<&[(Value, Value)]>

Extract the map pairs.

Source

pub fn map_get(&self, key: &str) -> Option<&Value>

Look up a string key in a Map value.

Source

pub fn is_null(&self) -> bool

True for Value::Null.
