确保参数是'nz_number'或引发DataFormatError
# File lib/net/imap.rb, line 1641
def ensure_nz_number(num)
return if valid_nz_number?(num)
msg = "nz_number must be non-zero unsigned 32-bit integer: #{num}"

在RFC 3501术语中，检查通过参数有效的“number”
# File lib/net/imap.rb, line 1615
def valid_number?(num)
# [RFC 3501]
# number = 1*DIGIT
# ; Unsigned 32-bit integer
# ; (0 <= n < 4,294,967,296)
num >= 0 && num < 4294967296
end
valid_nz_number?(num) Show source
在RFC 3501术语中，检查传递参数有效'nz_number'
# File lib/net/imap.rb, line 1624
def valid_nz_number?(num)
# [RFC 3501]
# nz-number = digit-nz *DIGIT
# ; Non-zero unsigned 32-bit integer
# ; (0 < n < 4,294,967,296)
num != 0 && valid_number?(num)
end
