1//! # Data Wrapper
2//! We use CPI calls to circumvent the 10kb log limit on Solana transactions.
3//! Instead of logging events to the runtime, we execute a CPI to the `wrapper` program
4//! where the log data is serialized into the instruction data.
5//!
6//! This works because CPI instruction data is never truncated. Logging information is
7//! vital to the functioning of compression. When compression logs are truncated, indexers can fallback to
8//! deserializing the CPI instruction data.
