Struct FileSource 

pub struct FileSource { /* private fields */ }

A ByteSource backed by a local file.

Uses a Mutex for interior mutability since Read+Seek requires &mut self but ByteSource’s read_range takes &self.

Implementations

impl FileSource

pub fn open(path: impl AsRef<Path>) -> Result<Self, CopcError>

Open a local file as a byte source.

Trait Implementations

impl ByteSource for FileSource

async fn read_range( &self, offset: u64, length: u64, ) -> Result<Vec<u8>, CopcError>

Read length bytes starting at offset.

async fn size(&self) -> Result<Option<u64>, CopcError>

Total size of the source in bytes, if known.

fn read_ranges( &self, ranges: &[(u64, u64)], ) -> impl Future<Output = Result<Vec<Vec<u8>>, CopcError>>

Read multiple ranges in one logical operation.
