alpaca-facade

alpaca-facade provides high-level convenience facades built on top of the lower-level alpaca-rust crates.

Current public surface:

• AlpacaData for cache-first raw market-data access plus option enrichment
• AlpacaDataConfig for pricing assumptions such as risk-free rate and dividend yield
• OptionChainRequest for reusable option-chain filters
• bridge helpers such as map_snapshot, map_live_snapshots, and resolve_positions_from_optionstrat_url

Use this crate when you want:

• a reusable alpaca-data + alpaca-option + alpaca-time composition layer
• raw market-data caching without rebuilding the adapter stack yourself
• option-chain and enriched option-snapshot convenience helpers

This crate intentionally does not include:

• application singletons
• environment bootstrapping or config-file loading
• strategy orchestration or provider fallback logic
