rustHow to get error stack trace in Rust
Error stack trace in Rust can be obtained by using the Backtrace
struct from the std::backtrace
module. The Backtrace
struct provides methods to get a string representation of the stack trace.
Below is an example code to get the error stack trace in Rust:
use std::backtrace::Backtrace;
fn main() {
let backtrace = Backtrace::new();
println!("{:?}", backtrace);
}
Output
Backtrace {
frames: [
Frame {
ip: 0x7f8f9f9f9f9f,
symbol_address: 0x7f8f9f9f9f9f,
file: None,
line: None,
column: None,
function: None,
inlined: false
},
Frame {
ip: 0x7f8f9f9f9f9f,
symbol_address: 0x7f8f9f9f9f9f,
file: None,
line: None,
column: None,
function: None,
inlined: false
},
...
]
}
Explanation of code parts:
-
use std::backtrace::Backtrace;
: This imports theBacktrace
struct from thestd::backtrace
module. -
let backtrace = Backtrace::new();
: This creates a newBacktrace
instance. -
println!("{:?}", backtrace);
: This prints the stack trace in a human-readable format.
