| name | A unique name for this target. | Name | required | |
| srcs | Files and/or directories or targets that provide `DirectoryPathInfo` to copy into the output directory. | List of labels | optional | `[]` |
| out | Path of the output directory, relative to this package.
If not set, the name of the target is used. | String | optional | `""` |
+| add_directory_to_runfiles | Whether to add the outputted directory to the target's runfiles. | Boolean | optional | `True` |
| allow_overwrites | If True, allow files to be overwritten if the same output file is copied to twice.
The order of srcs matters as the last copy of a particular file will win when overwriting. Performance of copy_to_directory will be slightly degraded when allow_overwrites is True since copies cannot be parallelized out as they are calculated. Instead all copy paths must be calculated before any copies can be started. | Boolean | optional | `False` |
| exclude_srcs_packages | List of Bazel packages (with glob support) to exclude from output directory.
Files in srcs are not copied to the output directory if the Bazel package of the file matches one of the patterns specified.
Forward slashes (`/`) should be used as path separators. A first character of `"."` will be replaced by the target's package path.
Files that have do not have matching Bazel packages are subject to subsequent filters and transformations to determine if they are copied and what their path in the output directory will be.
Globs are supported (see rule docstring above). | List of strings | optional | `[]` |
| exclude_srcs_patterns | List of paths (with glob support) to exclude from output directory.
Files in srcs are not copied to the output directory if their output directory path, after applying `root_paths`, matches one of the patterns specified.
Forward slashes (`/`) should be used as path separators.
Files that do not have matching output directory paths are subject to subsequent filters and transformations to determine if they are copied and what their path in the output directory will be.
