This package provides a basic logging library for smart contracts running on the Internet Computer (also known as canisters).
Macros declare_log_buffer
and log
are the core library interface.
The declare_log_buffer
macros creates a circular buffer of messages with the specified capacity.
The log
macro formats and appends messages to a buffer.
You can extract messages from the log buffer using the export
function.
```rust use iccanisterlog::{declarelogbuffer, export, log};
// Keep up to 100 last messages. declarelogbuffer!(name = LOG, capacity = 100);
fn sumandlog(x: u64, y: u64) -> u64 { let result = x.saturating_add(y); log!(LOG, "{} + {} = {}", x, y, result); result }
fn printlogentries() { for entry in export(&LOG) { println!("{}:{} {}", entry.file, entry.line, entry.message); } } ```
