Description
A secret value, like a password or other binary secret.
Synopsis
- newtype Value = Value (ManagedPtr Value)
- noValue :: Maybe Value
- valueGet :: (HasCallStack, MonadIO m) => Value -> m ByteString
- valueGetContentType :: (HasCallStack, MonadIO m) => Value -> m Text
- valueGetText :: (HasCallStack, MonadIO m) => Value -> m (Maybe Text)
- valueNew :: (HasCallStack, MonadIO m) => Text -> Int64 -> Text -> m Value
- valueNewFull :: (HasCallStack, MonadIO m) => Text -> Int64 -> Text -> DestroyNotify -> m Value
- valueRef :: (HasCallStack, MonadIO m) => Value -> m Value

Methods
get
Arguments
:: (HasCallStack, MonadIO m) | |
=> Value |
|
-> m ByteString | Returns: the secret data |
Get the secret data in the Value
. The value is not necessarily
null-terminated unless it was created with valueNew
or a
null-terminated string was passed to valueNewFull
.
getContentType
Arguments
:: (HasCallStack, MonadIO m) | |
=> Value |
|
-> m Text | Returns: the content type |
Get the content type of the secret value, such as <literal>text/plain</literal>.
getText
Arguments
:: (HasCallStack, MonadIO m) | |
=> Value |
|
-> m (Maybe Text) | Returns: the content type |
Get the secret data in the Value
if it contains a textual
value. The content type must be <literal>text/plain</literal>.
new
Arguments
:: (HasCallStack, MonadIO m) | |
=> Text |
|
-> Int64 |
|
-> Text |
|
-> m Value | Returns: the new |
Create a Value
for the secret data passed in. The secret data is
copied into non-pageable 'secure' memory.
If the length is less than zero, then secret
is assumed to be
null-terminated.
newFull
Arguments
:: (HasCallStack, MonadIO m) | |
=> Text |
|
-> Int64 |
|
-> Text |
|
-> DestroyNotify |
|
-> m Value | Returns: the new |
Create a Value
for the secret data passed in. The secret data is
not copied, and will later be freed with the destroy
function.
If the length is less than zero, then secret
is assumed to be
null-terminated.
ref
Arguments
:: (HasCallStack, MonadIO m) | |
=> Value |
|
-> m Value | Returns: the value |
Add another reference to the Value
. For each reference
valueUnref
should be called to unreference the value.
unref
Arguments
:: (HasCallStack, MonadIO m) | |
=> Value |
|
-> m () |
Unreference a Value
. When the last reference is gone, then
the value will be freed.
