A backtrace implementation written in Rust for Linux OS (ELF binaries). This is implemented using other Rust crates such as: - gimli - object - memmap-rs - addr2line - rustc-demangle
Currently working only on x86-64, x86 architectures and on libc and musl-libc platforms.
Add the crate dependency in the Cargo.toml
file.

backtrace-rust = "0.1"
Instantiate an object of type backtrace::Backtrace
and print it with the {:?}
format. Example:
```rust use backtrace_rust::backtrace::Backtrace;
fn main() { let bt = Backtrace::new(); // other code println!("{:?}", bt); } ```
There are 3 examples in the examples/
directory. Example of running:
$ cargo +nightly run --example complex_inline
