Struct BasisPoint 

pub struct BasisPoint {
    pub ts_ms: i64,
    pub value: f64,
    pub mark: f64,
    pub index: f64,
}

32 B record (LE): i64 ts_ms (8), f64 value (8), f64 mark (8), f64 index (8)

value = mark - index. The derived path (BasisDerived) always populates all four fields. The legacy WS path (no exchange emits StreamEvent::Basis today) populates mark = NaN, index = NaN.

Fields

ts_ms: i64

value: f64

basis = mark − index

mark: f64

index: f64

Trait Implementations

impl Clone for BasisPoint

fn clone(&self) -> BasisPoint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl DataPoint for BasisPoint

fn from_stream_event(ev: &StreamEvent) -> Option<Self>

WS path: no exchange emits StreamEvent::Basis with real data today. Populates mark = NaN, index = NaN for forward-compat if one ever does.

const RECORD_SIZE: usize = SIZE

On-disk record size in bytes. MUST be constant for the type.

fn encode(&self, out: &mut [u8])

Encode self to a fixed-size buffer (little-endian).

fn decode(bytes: &[u8]) -> Option<Self>

Decode from a fixed-size buffer. Returns None on malformed bytes.

fn timestamp_ms(&self) -> i64

Timestamp in milliseconds. Used for warm-start / range queries.

fn encode_blob(&self) -> Option<Vec<u8>>

Variable-length bytes to append to the companion .blob file.

fn decode_blob(header: &[u8], _blob: &[u8]) -> Option<Self>

Reconstruct Self from header bytes + blob slice.

fn blob_pointer_offset() -> Option<usize>

Some(offset) if the type uses blob storage; None otherwise.

impl Debug for BasisPoint

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for BasisPoint

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for BasisPoint

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
