Struct BacktraceSymbol

pub struct BacktraceSymbol { /* private fields */ }

Available on tokio_unstable and Linux and crate feature rt and crate feature taskdump and (AArch64 or s390x or x86 or x86-64) only.

A backtrace symbol.

This struct provides accessors for backtrace symbols, similar to backtrace::BacktraceSymbol.

Implementations

impl BacktraceSymbol

pub fn name_raw(&self) -> Option<&[u8]>

Return the raw name of the symbol.

pub fn name_demangled(&self) -> Option<&str>

Return the demangled name of the symbol.

pub fn addr(&self) -> Option<*mut c_void>

Returns the starting address of this symbol.

pub fn filename(&self) -> Option<&Path>

Returns the file name where this function was defined. If debuginfo is missing, this is likely to return None.

pub fn lineno(&self) -> Option<u32>

Returns the line number for where this symbol is currently executing.

If debuginfo is missing, this is likely to return None.

pub fn colno(&self) -> Option<u32>

Returns the column number for where this symbol is currently executing.

If debuginfo is missing, this is likely to return None.
