Struct Ticker 

pub struct Ticker { /* private fields */ }

Universal ticker - canonical representation across venues.

Backed by Arc<str> for O(1) clone in hot loops.

Implementations

impl Ticker

pub fn new( underlying: Underlying, quote: impl Into<String>, asset_type: AssetType, venue_type: VenueType, ) -> Self

pub fn with_exchange_hint(self, hint: impl Into<String>) -> Self

Set the exchange hint for provider formatting (#701).

pub fn underlying(&self) -> &Underlying

pub fn quote(&self) -> &str

pub fn asset_type(&self) -> AssetType

pub fn venue_type(&self) -> VenueType

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

Exchange suffix hint for provider formatting (e.g. “XETRA”, “AS”).

pub fn canonical(&self) -> String

Trait Implementations

impl Clone for Ticker

fn clone(&self) -> Ticker

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Ticker

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Ticker

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Ticker

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

Formats the value using the given formatter.

impl From<&Symbol> for Ticker

fn from(symbol: &Symbol) -> Self

Convert a Symbol to a Ticker, inferring asset class and venue.

• Crypto pairs (USDT, BTC, etc. quote/base) → Crypto + Cex
• Everything else → Equity + TradFi

impl FromStr for Ticker

fn from_str(s: &str) -> Result<Self, Self::Err>

Parse a BASE/QUOTE string into a Ticker.

Infers asset class heuristically:

• Crypto quotes (USDT, USDC, BTC, ETH, etc.) → Crypto
• USD/fiat quotes with crypto base (BTC, ETH, SOL, etc.) → Crypto
• USD/fiat quotes with non-crypto base → Equity

type Err = TickerError

The associated error which can be returned from parsing.

impl Hash for Ticker

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 Ticker

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

impl Serialize for Ticker

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
