Functions

erlang_file_name

</> 
pub fn erlang_file_name(stack_frame: StackFrame) -> String

Gets the erlang file name of the stack frame.

erlang_line_number

</> 
pub fn erlang_line_number(stack_frame: StackFrame) -> Int

Gets the ang erlline number of the stack frame.

erlang_module_name

</> 
pub fn erlang_module_name(stack_frame: StackFrame) -> String

Gets the erlang module name of the stack frame.

frame

</> 
pub fn frame(stack_trace: StackTrace, index: Int) -> StackFrame

Gets the stack frame at the given 0-based list index where 0 is the last stack frame and 1 is the second-to-last stack frame and size(stack_trace) - 1 is the first stack frame.

The StackFrame itself has an inverse index field that represents the index of the frame within the stack. see frame_by_stack_index.

frame_by_stack_index

</> 
pub fn frame_by_stack_index(
  stack_trace: StackTrace,
  index: Int,
) -> StackFrame

Gets the stack frame at the given 1-based stack index, where 1 is the first stack frame, 2 is the second stack frame, and size(stack_trace) is the last stack frame.

frame_to_string

</> 
pub fn frame_to_string(stack_frame: StackFrame) -> String

Converts a stack frame to a string.

function_arity

</> 
pub fn function_arity(stack_frame: StackFrame) -> Int

Gets the function arity of the stack frame.

function_name

</> 
pub fn function_name(stack_frame: StackFrame) -> String

Gets the function name of the stack frame.

gleam_module_name

</> 
pub fn gleam_module_name(stack_frame: StackFrame) -> String

Gets the potential gleam module name from the erlang stack frame.

main

</> 
pub fn main() -> Nil

This is a library and the main function exists as a placeholder if called as a function from the command line.

</> 
pub fn print_frame(stack_frame: StackFrame) -> Nil

Print a stack frame.

</> 
pub fn print_frame_with(
  stack_frame: StackFrame,
  context c: a,
) -> Nil

Print a stack frame with context.

</> 
pub fn print_trace(stack_trace: StackTrace) -> Nil

Print a stack trace.

</> 
pub fn print_trace_with(
  stack_trace: StackTrace,
  context c: a,
) -> Nil

Print a stack trace with context.

size

</> 
pub fn size(stack_trace: StackTrace) -> Int

Calculates the stack trace size.

stack_index

</> 
pub fn stack_index(stack_frame: StackFrame) -> Int

Gets the stack index within its parent stack frame.

trace

</> 
pub fn trace() -> StackTrace

Gets the stack trace of the current process.

trace_to_string

</> 
pub fn trace_to_string(stack_frame: StackTrace) -> String

Converts a stack trace to a string.
