[−][src]Struct splitfile::SplitFile
A reference to an open set of volumes on the filesystem.
An instance of SplitFile can be read and/or written in the same way as a
single file is via fs::File
, but with data allocated
across volumes.
Second and subsequent volumes written use the path and filename of the first volume, and append the extension ".n", where n is the index of each respective volume.
SplitFile implements Read, Write and Seek traits.
Implementations
impl SplitFile
[src]
pub fn open<P: AsRef<Path>>(path: P, volsize: u64) -> Result<SplitFile>
[src]
Attempts to open a file in read-only mode.
See the OpenOptions::open
method for more details.
pub fn create<P: AsRef<Path>>(path: P, volsize: u64) -> Result<SplitFile>
[src]
Opens a file in write-only mode.
This function will create a file if it does not exist, and will truncate it if it does.
