Struct BacktraceFrameFmt

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

A formatter for just one frame of a backtrace.

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

Implementations

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

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

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.

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

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<(), Error>

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<(), Error>

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.

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<(), Error>

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.

Trait Implementations

impl Drop for BacktraceFrameFmt<'_, '_, '_>

fn drop(&mut self)

Executes the destructor for this type.
