pub struct SymbolFormatter;

Symbol formatter for converting ParsedSymbol to unified symbol strings

Provides methods to format ParsedSymbol structures into their canonical unified symbol string representation.

Implementations

impl SymbolFormatter

pub fn format(parsed: &ParsedSymbol) -> String

Format a ParsedSymbol into a unified symbol string

Arguments

• parsed - The parsed symbol to format

Returns

Returns the unified symbol string in the appropriate format:

• Spot: BASE/QUOTE
• Swap: BASE/QUOTE:SETTLE
• Futures: BASE/QUOTE:SETTLE-YYMMDD

Examples

use ccxt_core::symbol::{ParsedSymbol, SymbolFormatter};
use ccxt_core::types::symbol::ExpiryDate;

// Spot symbol
let spot = ParsedSymbol::spot("BTC".to_string(), "USDT".to_string());
assert_eq!(SymbolFormatter::format(&spot), "BTC/USDT");

// Linear swap symbol
let swap = ParsedSymbol::linear_swap("ETH".to_string(), "USDT".to_string());
assert_eq!(SymbolFormatter::format(&swap), "ETH/USDT:USDT");

// Inverse swap symbol
let inverse = ParsedSymbol::inverse_swap("BTC".to_string(), "USD".to_string());
assert_eq!(SymbolFormatter::format(&inverse), "BTC/USD:BTC");

// Futures symbol
let expiry = ExpiryDate::new(24, 12, 31).unwrap();
let futures = ParsedSymbol::futures("BTC".to_string(), "USDT".to_string(), "USDT".to_string(), expiry);
assert_eq!(SymbolFormatter::format(&futures), "BTC/USDT:USDT-241231");
