Implementations

impl PosixWritableFile

pub fn flush_buffer(&mut self) -> Status

pub fn write_unbuffered(&mut self, data: *const u8, size: usize) -> Status

pub fn sync_dir_if_manifest(&mut self) -> Status

pub fn sync_fd(fd: i32, fd_path: &String, syncing_dir: bool) -> Status

| Ensures that all the caches associated with | the given file descriptor’s data are flushed | all the way to durable media, and can | withstand power failures. | | The path argument is only used to populate | the description string in the returned crate::Status | if an error occurs.

pub fn dirname(filename: &String) -> String

| Returns the directory name in a path pointing | to a file. | | Returns “.” if the path does not contain any | directory separator.

pub fn basename(filename: &String) -> Slice

| Extracts the file name from a path pointing | to a file. | | The returned Slice points to |filename|’s | data buffer, so it is only valid while | |filename| is alive and unchanged.

pub fn is_manifest(filename: &String) -> bool

| True if the given file is a manifest file. |

pub fn new(filename: String, fd: i32) -> Self
