pub enum FileBackedVolumeProviderRequest {
    Open {
        parent_directory_token: Handle,
        name: String,

Variants

Open

Opens a file as a block device and starts serving block requests.

name must refer to an existing file in the directory represented by parent_directory_token.

The block size of the device will match the underlying filesystem’s block size. If the file’s size is not a multiple of the block size, the apparent size of the device will be rounded down.

parent_directory_token is a token obtained via fuchsia.io.Directory/GetToken. The directory connection must have the MODIFY_DIRECTORY right.

Errors will be sent as an epitaph on server_end.
