begin
  ec.convert("\xa0")
rescue Encoding::UndefinedConversionError
  puts $!.error_char.dump   #=> "\xC2\xA0"
  p $!.error_char.encoding  #=> #<Encoding:UTF-8>
end

Returns a conversion path.

p Encoding::Converter.search_convpath("ISO-8859-1", "EUC-JP")
#=> [[#<Encoding:ISO-8859-1>, #<Encoding:UTF-8>],
#    [#<Encoding:UTF-8>, #<Encoding:EUC-JP>]]

Iterates over keys. Note that unlike other collections, each_key without block isn’t supported.

Iterates over values. Note that unlike other collections, each_value without block isn’t supported.

Calls the given block once for each byte in the stream.

Calls the block with each key/value pair:

res = Net::HTTP.get_response(hostname, '/todos/1')
res.each_header do |key, value|
  p [key, value] if key.start_with?('c')
end

Output:

["content-type", "application/json; charset=utf-8"]
["connection", "keep-alive"]
["cache-control", "max-age=43200"]
["cf-cache-status", "HIT"]
["cf-ray", "771d17e9bc542cf5-ORD"]

Returns an enumerator if no block is given.

Net::HTTPHeader#each is an alias for Net::HTTPHeader#each_header.

Calls the block with each field key:

res = Net::HTTP.get_response(hostname, '/todos/1')
res.each_key do |key|
  p key if key.start_with?('c')
end

Output:

"content-type"
"connection"
"cache-control"
"cf-cache-status"
"cf-ray"

Returns an enumerator if no block is given.

Net::HTTPHeader#each_name is an alias for Net::HTTPHeader#each_key.

Calls the block with each string field value:

res = Net::HTTP.get_response(hostname, '/todos/1')
res.each_value do |value|
  p value if value.start_with?('c')
end

Output:

"chunked"
"cf-q-config;dur=6.0000002122251e-06"
"cloudflare"

Returns an enumerator if no block is given.

Like each_header, but the keys are returned in capitalized form.

Net::HTTPHeader#canonical_each is an alias for Net::HTTPHeader#each_capitalized.
