堆栈跟踪

    Stack information representing execution context, with the following fields:

    • The name of the function containing the execution context.

    • linfo::Union{Core.MethodInstance, CodeInfo, Nothing}

      The MethodInstance containing the execution context (if it could be found).

    • line::Int

      The line number in the file containing the execution context.

    • True if the code is from C.

    • pointer::UInt64

      Representation of the pointer to the execution context as returned by backtrace.

    Base.StackTraces.StackTrace — Type

    1. StackTrace

    An alias for provided for convenience; returned by calls to stacktrace.

    Returns a stack trace in the form of a vector of StackFrames. (By default stacktrace doesn’t return C functions, but this can be enabled.) When called without specifying a trace, stacktrace first calls backtrace.

    source

    Base.StackTraces 中以下方法和类型不会被导出，需要显式调用，例如 StackTraces.lookup(ptr)。

    — Function

      Given a pointer to an execution context (usually generated by a call to backtrace), looks up stack frame context information. Returns an array of frame information for all functions inlined at that point, innermost function first.

      source

      — Function

      Takes a (a vector of StackFrames) and a function name (a Symbol) and removes the StackFrame specified by the function name from the StackTrace (also removing all frames above the specified function). Primarily used to remove StackTraces functions from the StackTrace prior to returning it.
