Trait ParseNumeric 

pub trait ParseNumeric {
    // Required methods
    fn parse_f64(&self) -> Option<f64>;
    fn parse_u64(&self) -> Option<u64>;
}

Convenience trait for parsing string numeric fields to native types.

TradeStation returns most numeric values as JSON strings. This trait provides ergonomic parsing on any type with a string field.

Example

use tradestation_api::market_data::ParseNumeric;

let value = "123.45";
assert_eq!(value.parse_f64(), Some(123.45));
assert_eq!("1000".parse_u64(), Some(1000));
assert_eq!("bad".parse_f64(), None);

Required Methods

fn parse_f64(&self) -> Option<f64>

Parse this string value as f64, returning None on failure.

fn parse_u64(&self) -> Option<u64>

Parse this string value as u64, returning None on failure.
