Parses a C struct’s members
Example:
require 'fiddle/import' include Fiddle::CParser #=> Object parse_struct_signature(['int i', 'char c']) #=> [[Fiddle::TYPE_INT, Fiddle::TYPE_CHAR], ["i", "c"]] parse_struct_signature(['char buffer[80]']) #=> [[[Fiddle::TYPE_CHAR, 80]], ["buffer"]]
Calls the block with each capitalized field name:
res = Net::HTTP.get_response(hostname, '/todos/1') res.each_capitalized_name do |key| p key if key.start_with?('C') end
Output:
"Content-Type" "Connection" "Cache-Control" "Cf-Cache-Status" "Cf-Ray"
The capitalization is system-dependent; see Case Mapping.
Returns an enumerator if no block is given.

Marshal
dumps exit locations to the given filename.
Usage:
If --yjit-exit-locations
is passed, a file named “yjit_exit_locations.dump” will automatically be generated.
If you want to collect traces manually, call dump_exit_locations
directly.
Note that calling this in a script will generate stats after the dump is created, so the stats data may include exits from the dump itself.
In a script call:
at_exit do RubyVM::YJIT.dump_exit_locations("my_file.dump") end
Then run the file with the following options:
ruby --yjit --yjit-trace-exits test.rb
Once the code is done running, use Stackprof to read the dump file. See Stackprof documentation for options.
Stop tracing object allocations.
Note that if ::trace_object_allocations_start
is called n-times, then tracing will stop after calling ::trace_object_allocations_stop
n-times.
Clear recorded tracing information.
The index to insert activated gem paths into the $LOAD_PATH. The activated gem’s paths are inserted before site lib directory by default.
