//! Logging utilities for Rust-based Solana programs.
//!
//! Logging is the main mechanism for getting debugging information out of
//! running Solana programs, and there are several functions available for doing
//! so efficiently, depending on the type of data being logged.
//!
//! The most common way to emit logs is through the [`msg!`] macro, which logs
//! simple strings, as well as [formatted strings][fs].
//!
//! [`msg!`]: crate::msg!
//! [fs]: https://doc.rust-lang.org/std/fmt/
//!
//! Logs can be viewed in multiple ways:
//!
//! - The `solana logs` command displays logs for all transactions executed on a
//!   network. Note though that transactions that fail during pre-flight
//!   simulation are not displayed here.
//! - When submitting transactions via [`RpcClient`], if Rust's own logging is
//!   active then the `solana_rpc_client` crate logs at the "debug" level any logs
//!   for transactions that failed during simulation. If using [`env_logger`]
//!   these logs can be activated by setting `RUST_LOG=solana_rpc_client=debug`.
//! - Logs can be retrieved from a finalized transaction by calling
//!   [`RpcClient::get_transaction`].
//! - Block explorers may display logs.
//!
//! [`RpcClient`]: https://docs.rs/solana-rpc-client/latest/solana_rpc_client/rpc_client/struct.RpcClient.html
//! [`env_logger`]: https://docs.rs/env_logger
//! [`RpcClient::get_transaction`]: https://docs.rs/solana-rpc-client/latest/solana_rpc_client/rpc_client/struct.RpcClient.html#method.get_transaction
//!
//! While most logging functions are defined in this module, [`Pubkey`]s can
//! also be efficiently logged with the [`Pubkey::log`] function.
//!
//! [`Pubkey`]: crate::pubkey::Pubkey
//! [`Pubkey::log`]: crate::pubkey::Pubkey::log
