Stack information representing execution context, with the following fields:

  • func::Symbol

    The name of the function containing the execution context.

  • linfo::Nullable{LambdaInfo}

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

  • file::Symbol

    The path to the file containing the execution context.

  • line::Int

    The line number in the file containing the execution context.

  • from_c::Bool

    True if the code is from C.

  • inlined::Bool

    True if the code is from an inlined frame.

  • pointer::Int64

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


An alias for Vector{StackFrame} provided for convenience; returned by calls to stacktrace and catch_stacktrace.

stacktrace([trace::Vector{Ptr{Void}},] [c_funcs::Bool=false]) → 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.

catch_stacktrace([c_funcs::Bool=false]) → StackTrace

Returns the stack trace for the most recent error thrown, rather than the current execution context.

The following methods and types in Base.StackTraces are not exported and need to be called e.g. as StackTraces.lookup(ptr).

lookup(pointer::Union{Ptr{Void}, UInt}) → Vector{StackFrame}

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.

remove_frames!(stack::StackTrace, name::Symbol)

Takes a StackTrace (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.
