Struct Symbol 

pub struct Symbol { /* private fields */ }

A trading symbol representing a base/quote currency pair.

Implementations

impl Symbol

pub fn base(&self) -> &str

Returns the base currency (e.g., “BTC” in BTC/USDT).

pub fn quote(&self) -> &str

Returns the quote currency (e.g., “USDT” in BTC/USDT).

pub fn canonical(&self) -> String

Returns the canonical BASE/QUOTE representation.

pub fn is_crypto(&self) -> bool

Returns true if this is likely a crypto pair.

Heuristic: checks both quote AND base currencies.

• Crypto quotes (USDT, USDC, BTC, ETH, etc.) → crypto
• Known crypto bases with fiat quote (BTC/USD, ETH/USD) → crypto
• Everything else → not crypto

Aligned with Ticker::FromStr inference logic (#2693).

Trait Implementations

impl Clone for Symbol

fn clone(&self) -> Symbol

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Symbol

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Symbol

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

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 Symbol

type Err = SymbolError

The associated error which can be returned from parsing.

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

Parses a string s to return a value of this type.

impl Hash for Symbol

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 Symbol

fn eq(&self, other: &Symbol) -> 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 Symbol

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Symbol
