Struct Capability 

pub struct Capability(/* private fields */);

Capability bits that a provider can declare.

Route a capability to specific providers using .route(Capability::QUOTE, [Provider::Fmp]). If no route is configured for a capability, only Yahoo is used, or EDGAR then Yahoo for Capability::FILINGS.

Implementations

impl Capability

pub const QUOTE: Self

Equity quote data — price, volume, market cap, fundamentals summary.

pub const CHART: Self

Historical OHLCV chart data across intervals and ranges.

pub const FUNDAMENTALS: Self

Financial statements — income, balance sheet, cash flow.

pub const CORPORATE: Self

Corporate events — news, recommendations, SEC filings metadata.

pub const OPTIONS: Self

Options chains and contract data.

pub const DISCOVERY: Self

Symbol discovery — search, screeners, exchange and ticker reference data.

pub const CRYPTO: Self

Cryptocurrency quotes and market data.

pub const ECONOMIC: Self

Macro-economic data series (FRED, GDP, CPI, etc.).

pub const CALENDAR: Self

Market-wide calendars — earnings, IPOs, dividends, splits, economic events.

pub const FOREX: Self

Foreign exchange currency pair quotes.

pub const INDICES: Self

Stock market index quotes (S&P 500, NASDAQ, etc.).

pub const FUTURES: Self

Futures contract quotes.

pub const COMMODITIES: Self

Commodity price quotes (gold, oil, etc.).

pub const MARKET: Self

Market-wide statistics — sector/industry performance and movers.

pub const FILINGS: Self

SEC EDGAR filing data.

pub const NONE: Self

The empty capability set — starting point for derived accumulation.

pub const fn union(self, other: Self) -> Self

Const-context union, for capability-set consts (std::ops::BitOr isn’t const-callable).

pub fn all() -> impl Iterator<Item = Self>

Every single-bit capability, in declaration order.

Combined sets are not included: this yields exactly the constants above.

pub const fn contains(self, other: Self) -> bool

Returns true if this capability set includes all bits in other.

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

Returns a short lowercase name for this capability (e.g., "quote", "chart").

Returns "unknown" for combined capability flags or unrecognised bits; Display spells combined sets out instead (e.g. "quote|chart").

impl Capability

pub fn candidate_providers(self) -> Vec<Provider>

Providers whose capabilities() declare this capability, regardless of which providers are actually configured/feature-enabled in this build.

Purely informational — used to make crate::FinanceError::NotSupported/ crate::FinanceError::NoProviderAvailable point at what would need to be enabled (feature flag) and/or routed (Providers::builder().route(...)).

Built-ins only. A registered custom provider never appears here, since Provider::capabilities cannot see an adapter’s accessors.

Trait Implementations

impl BitOr for Capability

type Output = Capability

The resulting type after applying the | operator.

fn bitor(self, rhs: Self) -> Self

Performs the | operation.

impl Clone for Capability

fn clone(&self) -> Capability

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Capability

impl Debug for Capability

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

Formats the value using the given formatter.

impl Display for Capability

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

Single capabilities print their name; combined sets are spelled out |-separated (e.g. "quote|chart") rather than collapsing to "unknown".

impl Eq for Capability

impl Hash for Capability

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Capability

fn eq(&self, other: &Capability) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
