Struct Snapshot 

struct Snapshot {
    state: MarketState,
    provenance: BTreeMap<CurveId, Arc<CurveProvenance>>,
    refits: BTreeMap<CreditCurveId, Arc<SurvivalRefit>>,
    curve_refits: BTreeMap<CurveId, Arc<CurveRefit>>,
    misdated: BTreeMap<(&'static str, String), ReferenceDateMismatch>,
    fetched: Option<Arc<MarketData>>,
    source_recipes: BTreeMap<CollateralSpec, Option<CurveRecipe>>,
}

One date’s snapshot, set aside while the market is at another date: the state as of that date (its fixings excepted, which live in the history), the ladders and refits behind its curves, its misdated record, and the data it was fetched from.

Fields

state: MarketState

provenance: BTreeMap<CurveId, Arc<CurveProvenance>>

refits: BTreeMap<CreditCurveId, Arc<SurvivalRefit>>

curve_refits: BTreeMap<CurveId, Arc<CurveRefit>>

misdated: BTreeMap<(&'static str, String), ReferenceDateMismatch>

fetched: Option<Arc<MarketData>>

source_recipes: BTreeMap<CollateralSpec, Option<CurveRecipe>>

Implementations

impl Snapshot

fn is_empty(&self) -> bool

Whether the snapshot holds nothing a valuation reads.

Trait Implementations

impl Clone for Snapshot

fn clone(&self) -> Snapshot

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Snapshot

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

Formats the value using the given formatter.

impl Default for Snapshot

fn default() -> Snapshot

Returns the “default value” for a type.

impl PartialEq for Snapshot

A set-aside snapshot is its state: its ladders, refits and records are how it was built, as for the current one.

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