Struct opendal::raw::oio::FlatLister

pub struct FlatLister<A: Access, L> { /* private fields */ }

FlatLister will walk dir in bottom up way:

• List nested dir first
• Go back into parent dirs one by one

Given the following file tree:

.
├── dir_x/
│   ├── dir_y/
│   │   ├── dir_z/
│   │   └── file_c
│   └── file_b
└── file_a

ToFlatLister will output entries like:

dir_x/dir_y/dir_z/file_c
dir_x/dir_y/dir_z/
dir_x/dir_y/file_b
dir_x/dir_y/
dir_x/file_a
dir_x/

Note

There is no guarantee about the order between files and dirs at the same level. We only make sure the nested dirs will show up before parent dirs.

Especially, for storage services that can’t return dirs first, ToFlatLister may output parent dirs’ files before nested dirs, this is expected because files always output directly while listing.

Implementations

impl<A, L> FlatLister<A, L>

where A: Access,

pub fn new(acc: A, path: &str) -> FlatLister<A, L>

Create a new flat lister

Trait Implementations

impl<A, P> BlockingList for FlatLister<A, P>

where A: Access<BlockingLister = P>, P: BlockingList,

fn next(&mut self) -> Result<Option<Entry>>

Fetch a new page of Entry

impl<A, L> List for FlatLister<A, L>

where A: Access<Lister = L>, L: List,

async fn next(&mut self) -> Result<Option<Entry>>

Fetch a new page of Entry

impl<A: Access, L> Send for FlatLister<A, L>

Safety

wasm32 is a special target that we only have one event-loop for this FlatLister.

impl<A: Access, L> Sync for FlatLister<A, L>

Safety

We will only take &mut Self reference for FsLister.
