Make sure the trust directory exists. If it does exist, make sure it’s actually a directory. If not, then create it with the appropriate permissions.
@@foo = 1 ^^^^^^^^^
@@foo, @@bar = 1 ^^^^^ ^^^^^
Foo += bar ^^^^^^^^^^^

Foo ||= bar ^^^^^^^^^^^^
Foo::Bar = 1 ^^^^^^^^^^^^
Foo::Foo, Bar::Bar = 1 ^^^^^^^^ ^^^^^^^^
$foo = 1 ^^^^^^^^

Like Enumerable#zip
, but chains operation to be lazy-evaluated. However, if a block is given to zip, values are enumerated immediately.
Return the length of the hash value in bytes.
Return the length of the hash value (the digest) in bytes.
Digest::SHA256.new.digest_length * 8 # => 256 Digest::SHA384.new.digest_length * 8 # => 384 Digest::SHA512.new.digest_length * 8 # => 512
For example, digests produced by Digest::SHA256
will always be 32 bytes (256 bits) in size.
Returns the Fiddle::Pointer
of this handle.
Get the underlying pointer for ruby object val
and return it as a Fiddle::Pointer
object.
Generates a random prime number of bit length bits. If safe is set to true
, generates a safe prime. If add is specified, generates a prime that fulfills condition p % add = rem
.
Returns the output size of the digest, i.e. the length in bytes of the final message digest result.
digest = OpenSSL::Digest.new('SHA1') puts digest.digest_length # => 20
Sends the given command to this engine.
Raises an EngineError
if the command fails.
Called when the document starts with the declared version
, tag_directives
, if the document is implicit
.
version
will be an array of integers indicating the YAML
version being dealt with, tag_directives
is a list of tuples indicating the prefix and suffix of each tag, and implicit
is a boolean indicating whether the document is started implicitly.
Given the following YAML:
%YAML 1.1 %TAG ! tag:tenderlovemaking.com,2009: --- !squee
The parameters for start_document
must be this:
version # => [1, 1] tag_directives # => [["!", "tag:tenderlovemaking.com,2009:"]] implicit # => false
Called when a sequence is started.
anchor
is the anchor associated with the sequence or nil. tag
is the tag associated with the sequence or nil. implicit
a boolean indicating whether or not the sequence was implicitly started. style
is an integer indicating the list style.
See the constants in Psych::Nodes::Sequence
for the possible values of style
.
Here is a YAML
document that exercises most of the possible ways this method can be called:
--- - !!seq [ a ] - &pewpew - b
The above YAML
document consists of three lists, an outer list that contains two inner lists. Here is a matrix of the parameters sent to represent these lists:
# anchor tag implicit style [nil, nil, true, 1 ] [nil, "tag:yaml.org,2002:seq", false, 2 ] ["pewpew", nil, true, 1 ]
