Struct backtrace::BacktraceFrameFmt

pub struct BacktraceFrameFmt<'fmt, 'a, 'b> { /* fields omitted */ }

A formatter for just one frame of a backtrace.

This type is created by the BacktraceFmt::frame function.

Methods

impl<'_, '_, '_> BacktraceFrameFmt<'_, '_, '_>

pub fn backtrace_frame(&mut self, frame: &BacktraceFrame) -> Result

Prints a BacktraceFrame with this frame formatter.

This will recusrively print all BacktraceSymbol instances within the BacktraceFrame.

Required features

This function requires the std feature of the backtrace crate to be enabled, and the std feature is enabled by default.

pub fn backtrace_symbol(
    &mut self,
    frame: &BacktraceFrame,
    symbol: &BacktraceSymbol
) -> Result

Prints a BacktraceSymbol within a BacktraceFrame.

Required features

This function requires the std feature of the backtrace crate to be enabled, and the std feature is enabled by default.

pub fn symbol(&mut self, frame: &Frame, symbol: &Symbol) -> Result

Prints a raw traced Frame and Symbol, typically from within the raw callbacks of this crate.

pub fn print_raw(
    &mut self,
    frame_ip: *mut c_void,
    symbol_name: Option<SymbolName>,
    filename: Option<BytesOrWideString>,
    lineno: Option<u32>
) -> Result

Adds a raw frame to the backtrace output.

This method, unlike the previous, takes the raw arguments in case they're being source from different locations. Note that this may be called multiple times for one frame.
