If the stream begins with a BOM (byte order marker), consumes the BOM and sets the external encoding accordingly; returns the result encoding if found, or nil otherwise:
File.write('t.tmp', "\u{FEFF}abc") io = File.open('t.tmp', 'rb') io.set_encoding_by_bom # => #<Encoding:UTF-8> io.close File.write('t.tmp', 'abc') io = File.open('t.tmp', 'rb') io.set_encoding_by_bom # => nil io.close
Raises an exception if the stream is not binmode or its encoding has already been set.
Sets the encoding according to the BOM (Byte Order Mark) in the string.
Returns self if the BOM is found, otherwise +nil.
Starts tracing object allocations.
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.
The index to insert activated gem paths into the $LOAD_PATH. The activated gem’s paths are inserted before site lib directory by default.
This integer returns the maximum level of data structure nesting in the generated JSON, max_nesting = 0 if no maximum is checked.
This sets the maximum level of data structure nesting in the generated JSON to the integer depth, max_nesting = 0 if no maximum should be checked.
When *, **, &, or … are used as an argument in a method call, we check if they were allowed by the current context. To determine that we build this lookup table.

Extracts ifindex from IPV6_PKTINFO ancillary data.
IPV6_PKTINFO is defined by RFC 3542.
addr = Addrinfo.ip("::1") ifindex = 0 ancdata = Socket::AncillaryData.ipv6_pktinfo(addr, ifindex) p ancdata.ipv6_pktinfo_ifindex #=> 0
Sets the encoding to be used for the response body; returns the encoding.
The given value may be:
An Encoding object.
The name of an encoding.
An alias for an encoding name.
See Encoding.
Examples:
http = Net::HTTP.new(hostname) http.response_body_encoding = Encoding::US_ASCII # => #<Encoding:US-ASCII> http.response_body_encoding = 'US-ASCII' # => "US-ASCII" http.response_body_encoding = 'ASCII' # => "ASCII"
