Required methods

#[must_use]pub fn open_file<'life0, 'life1, 'async_trait>(
    &'life0 self,
    filename: &'life1 str,
    touch: bool
) -> Pin<Box<dyn Future<Output = Result<Box<dyn WALFile>, ()>> + 'async_trait>> where
    'life0: 'async_trait,
    'life1: 'async_trait,
    Self: 'async_trait, [src]

Open a file given the filename, create the file if not exists when touch is true.

#[must_use]pub fn remove_file<'life0, 'async_trait>(
    &'life0 self,
    filename: String
) -> Pin<Box<dyn Future<Output = Result<(), ()>> + 'async_trait>> where
    'life0: 'async_trait,
    Self: 'async_trait, [src]

Unlink a file given the filename.

pub fn enumerate_files(&self) -> Result<Self::FileNameIter, ()>[src]

Enumerate all WAL filenames. It should include all WAL files that are previously opened (created) but not removed. The list could be unordered.
