Struct CallerInfo 

pub struct CallerInfo {
    pub file: String,
    pub line: u32,
    pub function: String,
}

Caller information extracted from the call stack.

Source file path.

line: u32

Line number.

Function name.

Implementations

impl CallerInfo

pub fn capture(skip: usize) -> Option<Self>

Extracts caller information from the current call stack.

The skip parameter indicates how many frames to skip from the logging infrastructure to find the actual caller.

Performance Warning

This method captures a full stack backtrace and performs symbol resolution, which is a very expensive operation (~100μs or more). Avoid calling this in hot paths or production code.

Typical overhead: 100-1000x slower than a normal log call.
