Private setter for filter val.
Invoked by IO.select to ask whether the specified descriptors are ready for specified events within the specified timeout.
Expected to return the 3-tuple of Array of IOs that are ready.
Invoked by Timeout.timeout to execute the given block within the given duration. It can also be invoked directly by the scheduler or user code.
Attempt to limit the execution time of a given block to the given duration if possible. When a non-blocking operation causes the block‘s execution time to exceed the specified duration, that non-blocking operation should be interrupted by raising the specified exception_class constructed with the given exception_arguments.
General execution timeouts are often considered risky. This implementation will only interrupt non-blocking operations. This is by design because it’s expected that non-blocking operations can fail for a variety of unpredictable reasons, so applications should already be robust in handling these conditions and by implication timeouts.
However, as a result of this design, if the block does not invoke any non-blocking operations, it will be impossible to interrupt it. If you desire to provide predictable points for timeouts, consider adding +sleep(0)+.
If the block is executed successfully, its result will be returned.
The exception will typically be raised using Fiber#raise.
Returns the one-character string which cause Encoding::UndefinedConversionError.
ec = Encoding::Converter.new("ISO-8859-1", "EUC-JP") begin ec.convert("\xa0") rescue Encoding::UndefinedConversionError puts $!.error_char.dump #=> "\xC2\xA0" p $!.error_char.encoding #=> #<Encoding:UTF-8> end
primitive_errinfo returns important information regarding the last error as a 5-element array:
[result, enc1, enc2, error_bytes, readagain_bytes]
result is the last result of primitive_convert.
Other elements are only meaningful when result is :invalid_byte_sequence, :incomplete_input or :undefined_conversion.
enc1 and enc2 indicate a conversion step as a pair of strings. For example, a converter from EUC-JP to ISO-8859-1 converts a string as follows: EUC-JP -> UTF-8 -> ISO-8859-1. So [enc1, enc2] is either [“EUC-JP”, “UTF-8”] or [“UTF-8”, “ISO-8859-1”].
error_bytes and readagain_bytes indicate the byte sequences which caused the error. error_bytes is discarded portion. readagain_bytes is buffered portion which is read again on next conversion.
Example:
# \xff is invalid as EUC-JP. ec = Encoding::Converter.new("EUC-JP", "Shift_JIS") ec.primitive_convert(src="\xff", dst="", nil, 10) p ec.primitive_errinfo #=> [:invalid_byte_sequence, "EUC-JP", "Shift_JIS", "\xFF", ""] # HIRAGANA LETTER A (\xa4\xa2 in EUC-JP) is not representable in ISO-8859-1. # Since this error is occur in UTF-8 to ISO-8859-1 conversion, # error_bytes is HIRAGANA LETTER A in UTF-8 (\xE3\x81\x82). ec = Encoding::Converter.new("EUC-JP", "ISO-8859-1") ec.primitive_convert(src="\xa4\xa2", dst="", nil, 10) p ec.primitive_errinfo #=> [:undefined_conversion, "UTF-8", "ISO-8859-1", "\xE3\x81\x82", ""] # partial character is invalid ec = Encoding::Converter.new("EUC-JP", "ISO-8859-1") ec.primitive_convert(src="\xa4", dst="", nil, 10) p ec.primitive_errinfo #=> [:incomplete_input, "EUC-JP", "UTF-8", "\xA4", ""] # Encoding::Converter::PARTIAL_INPUT prevents invalid errors by # partial characters. ec = Encoding::Converter.new("EUC-JP", "ISO-8859-1") ec.primitive_convert(src="\xa4", dst="", nil, 10, Encoding::Converter::PARTIAL_INPUT) p ec.primitive_errinfo #=> [:source_buffer_empty, nil, nil, nil, nil] # \xd8\x00\x00@ is invalid as UTF-16BE because # no low surrogate after high surrogate (\xd8\x00). # It is detected by 3rd byte (\00) which is part of next character. # So the high surrogate (\xd8\x00) is discarded and # the 3rd byte is read again later. # Since the byte is buffered in ec, it is dropped from src. ec = Encoding::Converter.new("UTF-16BE", "UTF-8") ec.primitive_convert(src="\xd8\x00\x00@", dst="", nil, 10) p ec.primitive_errinfo #=> [:invalid_byte_sequence, "UTF-16BE", "UTF-8", "\xD8\x00", "\x00"] p src #=> "@" # Similar to UTF-16BE, \x00\xd8@\x00 is invalid as UTF-16LE. # The problem is detected by 4th byte. ec = Encoding::Converter.new("UTF-16LE", "UTF-8") ec.primitive_convert(src="\x00\xd8@\x00", dst="", nil, 10) p ec.primitive_errinfo #=> [:invalid_byte_sequence, "UTF-16LE", "UTF-8", "\x00\xD8", "@\x00"] p src #=> ""
Inserts string into the encoding converter. The string will be converted to the destination encoding and output on later conversions.
If the destination encoding is stateful, string is converted according to the state and the state is updated.
This method should be used only when a conversion error occurs.

Returns the trailing (‘parameters’) part of the value of field 'Content-Type', or nil if no such field exists; see Content-Type response header:
res = Net::HTTP.get_response(hostname, '/todos/1') res['content-type'] # => "application/json; charset=utf-8" res.type_params # => {"charset"=>"utf-8"}
Enumerates the trusted certificates via Gem::Security::TrustDir.
If response is an HTTP Success (2XX) response, yields the response if a block was given or shows the response body to the user.
If the response was not successful, shows an error to the user including the error_prefix and the response body. If the response was a permanent redirect, shows an error to the user including the redirect location.
Displays an error statement to the error output location. Asks a question if given.
Displays a warning statement to the warning output location. Asks a question if given.
