Types

ExitReason

All reasons an that an erlang process might by the runtime.

http://erlang.org/documentation/doc-9.3/doc/reference_manual/errors.html#exit_reasons Note erlang:exit and erlang:error can be called with any term. Therefore when captureing errors always make sure to safely cast to this type, i.e. using cast_exit_reason

pub type ExitReason {
  Badarg
  Badarith
  Badmatch(Dynamic)
  FunctionClause
  CaseClause(Dynamic)
  IfClause
  TryClause(Dynamic)
  Undef
  Badfun(Dynamic)
  Badarity(Dynamic)
  TimeoutValue
  Noproc
  Nocatch(Dynamic)
  SystemLimit
}

Stacktrace

A stacktrace data structure

pub type Stacktrace =
  List(tuple(Atom, String, Int, String, Int))

Functions

binary_to_term

pub fn binary_to_term(binary: BitString) -> Result(Dynamic, Nil)

cast_exit_reason

pub fn cast_exit_reason(
  raw: Dynamic,
) -> Result(ExitReason, String)

Safely transform dynamic to exit reason type

cast_stacktrace

pub fn cast_stacktrace(
  raw: Dynamic,
) -> Result(List(tuple(Atom, String, Int, String, Int)), String)

Safely cast a dynamic stacktrace to typed data.

format

pub fn format(term: a) -> String

Return a string representation of any term

term_to_binary

pub external fn term_to_binary(a) -> BitString

unsafe_binary_to_term

pub fn unsafe_binary_to_term(
  binary: BitString,
) -> Result(Dynamic, Nil)
