pub struct BacktraceFrameFmt<'fmt, 'a, 'b> { /* private fields */ }
Expand description

A formatter for just one frame of a backtrace.

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

Implementations§

source§

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

source

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

Prints a BacktraceFrame with this frame formatter.

This will recursively 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.

source

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.

source

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.

source

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.

source

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

Adds a raw frame to the backtrace output, including column information.

This method, like 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.
