Functions

func Indices

func Indices(stack pruntime.Stack) (isPanic bool, recoveryIndex, panicIndex int)

Indices examines a stack to see if it includes a panic. Thread-safe

• isPanic is true if the stack includes a panic
• stack[recoveryIndex] is the code line of the deferred function containing recovery() invocation
• stack[panicIndex] is the code line causing the panic located in the function deferring or any code that function invokes
• for panic detection to work, the code line of defer() invocation must be included in stack
• note: the location in the deferring function is returned as the last line of the deferring function
• pruntime.Stack is the parsed output of runtime.Stack

func PanicDetectorValues

func PanicDetectorValues() (deferS, panicS string)

PanicDetectorValues is used by [whynotpanic.WhyNotPanic] to explain panic detection
