Crate paft_core 

Core infrastructure utilities for the paft ecosystem.

This crate provides:

• Workspace-wide error type PaftError
• Macros for canonical string enums (open/closed) and Display via code()
• Reusable serde helpers for common timestamp encodings
• Optional re-exports for lightweight dataframe traits

Quickstart

use paft_core::{PaftError, string_enum_closed_with_code, impl_display_via_code};

// Define a closed string enum with canonical codes and parsing
#[derive(Debug, Clone, Copy, PartialEq, Eq, Hash)]
enum Side { Buy, Sell }
paft_core::string_enum_closed_with_code!(
    Side, "Side",
    { "BUY" => Side::Buy, "SELL" => Side::Sell }
);
paft_core::impl_display_via_code!(Side);

assert_eq!(Side::Buy.code(), "BUY");
assert_eq!("sell".parse::<Side>().unwrap(), Side::Sell);
assert!(matches!("".parse::<Side>(), Err(PaftError::InvalidEnumValue { .. })));

Feature flags

• dataframe: re-export dataframe traits from paft-utils

Serde helpers

See serde_helpers for helpers like ts_seconds_vec and ts_seconds_option.

Re-exports
