erlang module wrapper for providing tracing facility.

Description

erlang module wrapper for providing tracing facility.

The tracing facility is based on passage.

Data Types

spawn_option()

spawn_option() = {span, passage:maybe_span()} | {span_reference_type, passage:ref_type()} | (ErlangSpawnOption::term())

span: The current span. This is used as the parent span of the spawned process. The default value is passage:maybe_span().
span_reference_type: The span reference type between the current span and the span of the spawned process. The default value is follows_from.
ErlangSpawnOption: Other options defined in erlang module. See the description of erlang:spawn_opt/4 for more details.

spawn_options()

spawn_options() = [spawn_option()]

Options for spawn_opt functions.

Function Details

spawn/1

spawn(Fun::function()) -> pid()

Equivalent to spawn_opt(Fun, []).

spawn/2

spawn(Node::node(), Fun::function()) -> pid()

Equivalent to spawn_opt(Node, Fun, []).

spawn/3

spawn(Module::module(), Function::atom(), Args::[term()]) -> pid()

Equivalent to spawn_opt(Module, Function, Args, []).

spawn/4

spawn(Node::node(), Module::module(), Function::atom(), Args::[term()]) -> pid()

Equivalent to spawn_opt(Node, Module, Function, Args, []).

spawn_link/1

spawn_link(Fun::function()) -> pid()

Equivalent to spawn_opt(Fun, [link]).

spawn_link/2

spawn_link(Node::node(), Fun::function()) -> pid()

Equivalent to spawn_opt(Node, Fun, [link]).

spawn_link/3

spawn_link(Module::module(), Function::atom(), Args::[term()]) -> pid()

Equivalent to spawn_opt(Module, Function, Args, [link]).

spawn_link/4

spawn_link(Node::node(), Module::module(), Function::atom(), Args::[term()]) -> pid()

Equivalent to spawn_opt(Node, Module, Function, Args, [link]).

spawn_monitor/1

spawn_monitor(Fun::function()) -> {pid(), reference()}

Equivalent to spawn_opt(Fun, [monitor]).

spawn_monitor/3

spawn_monitor(Module::module(), Function::atom(), Args::[term()]) -> {pid(), reference()}

Equivalent to spawn_opt(Module, Function, Args, [monitor]).

spawn_opt/2

spawn_opt(Fun::function(), Options::spawn_options()) -> pid() | {pid(), reference()}

The same as erlang:spawn_opt/2 except for propagating the current span to the spawned process.

The propagated span is saved in the process dictionary of the spawned process. So the functions of passage_pd module can be used in the process.

spawn_opt/3

spawn_opt(Node::node(), Fun::function(), Options::spawn_options()) -> pid() | {pid(), reference()}

The same as erlang:spawn_opt/3 except for propagating the current span to the spawned process.

The propagated span is saved in the process dictionary of the spawned process. So the functions of passage_pd module can be used in the process.

spawn_opt/4

spawn_opt(Module::module(), Function::atom(), Args::[term()], Options::spawn_options()) -> pid() | {pid(), reference()}

Equivalent to spawn_opt(fun () -> apply(Module, Function, Args) end, Options).

spawn_opt/5

spawn_opt(Node::node(), Module::module(), Function::atom(), Args::[term()], Options::spawn_options()) -> pid() | {pid(), reference()}

Equivalent to spawn_opt(Node, fun () -> apply(Module, Function, Args) end, Options).
