Shortcut for defining multiple delegator methods, but with no provision for using a different name. The following two code samples have the same effect:
def_delegators :@records, :size, :<<, :map def_delegator :@records, :size def_delegator :@records, :<< def_delegator :@records, :map
Returns whether or not the struct of type type
contains member
. If it does not, or the struct type can’t be found, then false is returned. You may optionally specify additional headers
in which to look for the struct (in addition to the common header files).
If found, a macro is passed as a preprocessor constant to the compiler using the type name and the member name, in uppercase, prepended with HAVE_
.
For example, if have_struct_member('struct foo', 'bar')
returned true, then the HAVE_STRUCT_FOO_BAR
preprocessor macro would be passed to the compiler.
HAVE_ST_BAR
is also defined for backward compatibility.
The line number in the source code where this AST’s text began.
The column number in the source code where this AST’s text began.
Returns the security level for the context.
See also OpenSSL::SSL::SSLContext#security_level=
.
Sets the security level for the context. OpenSSL
limits parameters according to the level. The “parameters” include: ciphersuites, curves, key sizes, certificate signature algorithms, protocol version and so on. For example, level 1 rejects parameters offering below 80 bits of security, such as ciphersuites using MD5 for the MAC or RSA keys shorter than 1024 bits.
Note that attempts to set such parameters with insufficient security are also blocked. You need to lower the level first.
This feature is not supported in OpenSSL
< 1.1.0, and setting the level to other than 0 will raise NotImplementedError
. Level 0 means everything is permitted, the same behavior as previous versions of OpenSSL
.
See the manpage of SSL_CTX_set_security_level(3) for details.
A non-blocking version of sysread
. Raises an SSLError
if reading would block. If “exception: false” is passed, this method returns a symbol of :wait_readable, :wait_writable, or nil, rather than raising an exception.
Reads length bytes from the SSL
connection. If a pre-allocated buffer is provided the data will be written into it.
Writes string to the SSL
connection in a non-blocking manner. Raises an SSLError
if writing would block.
Returns the result of the peer certificates verification. See verify(1) for error values and descriptions.
If no peer certificate was presented X509_V_OK is returned.
Returns the protocol string that was finally selected by the client during the handshake.
Converts the name to DER encoding
Returns the error string corresponding to the error code retrieved by error
.
Encodes this ASN1Data
into a DER-encoded String
value. The result is DER-encoded except for the possibility of indefinite length forms. Indefinite length forms are not allowed in strict DER, so strictly speaking the result of such an encoding would be a BER-encoding.
See ASN1Data#to_der
for details.
