FUNCTIONS
None are exported by default, but they are exportable.
empty_trash() -> [status, msg, result, meta]
Empty trash.
No arguments.
Return value:
Returns an enveloped result (an array). First element (status) is an integer containing HTTP status code (200 means OK, 4xx caller error, 5xx function error). Second element (msg) is a string containing error message, or 'OK' if status is 200. Third element (result) is optional, the actual result. Fourth element (meta) is called result metadata and is optional, a hash that contains extra information.
list_trash_contents() -> [status, msg, result, meta]
List contents of trash directory.
No arguments.
Return value:
Returns an enveloped result (an array). First element (status) is an integer containing HTTP status code (200 means OK, 4xx caller error, 5xx function error). Second element (msg) is a string containing error message, or 'OK' if status is 200. Third element (result) is optional, the actual result. Fourth element (meta) is called result metadata and is optional, a hash that contains extra information.
trash(%args) -> [status, msg, result, meta]
Trash a file.
Fixed state: path does not exist.
Fixable state: path exists.
This function supports undo operation. This function supports dry-run operation. This function is idempotent (repeated invocations with same arguments has the same effect as single invocation). This function requires transactions.
Arguments ('*' denotes required arguments):
path => str
Special arguments:
-dry_run => bool
Pass -dry_run=>1 to enable simulation mode.
-tx_action => str
You currently can set this to 'rollback'. Usually you do not have to pass this yourself, Perinci::Access::InProcess will do it for you. For more details on transactions, see Rinci::function::Transaction.
-tx_manager => obj
Instance of transaction manager object, usually Perinci::Tx::Manager. Usually you do not have to pass this yourself, Perinci::Access::InProcess will do it for you. For more details on transactions, see Rinci::function::Transaction.
-undo_action => str
To undo, pass -undo_action=>'undo' to function. You will also need to pass -undo_data, unless you use transaction. For more details on undo protocol, see Rinci::function::Undo.
-undo_data => array
Required if you want undo and you do not use transaction. For more details on undo protocol, see Rinci::function::Undo.
Return value:
Returns an enveloped result (an array). First element (status) is an integer containing HTTP status code (200 means OK, 4xx caller error, 5xx function error).
