Struct IndexCompositionProto 

pub struct IndexCompositionProto {
    pub object_class: String,
    pub version: String,
    pub uuid: Option<UuidProto>,
    pub as_of: Option<LocalTimestampProto>,
    pub is_link: bool,
    pub valid_from: Option<LocalTimestampProto>,
    pub valid_to: Option<LocalTimestampProto>,
    pub index_security: Option<SecurityProto>,
    pub effective_date: Option<LocalDateProto>,
    pub constituents: Vec<IndexConstituentProto>,
    pub index_divisor: Option<DecimalValueProto>,
    pub notes: String,
}

A point-in-time snapshot of an equity index’s constituent securities and weights.

Temporal model (identical to PriceProto): uuid — stable identity for this composition record as_of — the timestamp this composition was observed / recorded valid_from — bitemporal: when this record became system-valid valid_to — bitemporal: when this record was superseded is_link — if true, only uuid is meaningful; resolve via GetByIds

A new IndexCompositionProto is created whenever the index is rebalanced. The effective_date field marks the business date the new composition took effect. To find the composition active on a given date D, query for the most recent record where effective_date <= D.

Fields

object_class: String

version: String

uuid: Option<UuidProto>

Primary Key (same temporal pattern as SecurityProto and PriceProto)

as_of: Option<LocalTimestampProto>

is_link: bool

valid_from: Option<LocalTimestampProto>

valid_to: Option<LocalTimestampProto>

index_security: Option<SecurityProto>

The index security this composition belongs to (EQUITY_INDEX_SECURITY type). Typically is_link = true; resolve via SecurityService.GetByIds.

effective_date: Option<LocalDateProto>

The calendar date on which this composition became effective (the rebalance date). Temporal lookup key: given as_of_date D, return the composition where effective_date <= D, ordered by effective_date DESC, LIMIT 1.

constituents: Vec<IndexConstituentProto>

The full list of constituents at this rebalance point.

index_divisor: Option<DecimalValueProto>

For price-weighted indices (e.g. DJIA), the divisor at this rebalance point. Divisors change when constituents change or corporate actions occur. index_level = sum(price_i * shares_i) / index_divisor

notes: String

Free-form notes (e.g. “Quarterly rebalance — removed XYZ, added ABC”).

Trait Implementations

impl Clone for IndexCompositionProto

fn clone(&self) -> IndexCompositionProto

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IndexCompositionProto

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

Formats the value using the given formatter.

impl Default for IndexCompositionProto

fn default() -> Self

Returns the “default value” for a type.

impl Message for IndexCompositionProto

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge<B>(&mut self, buf: B) -> Result<(), DecodeError>

where B: Buf, Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited<B>(&mut self, buf: B) -> Result<(), DecodeError>

where B: Buf, Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for IndexCompositionProto

fn eq(&self, other: &IndexCompositionProto) -> 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.
