Struct LazyFileHandle 

pub struct LazyFileHandle { /* private fields */ }

Lazy file handle that fetches ranges on demand via HTTP range requests Does NOT load the entire file into memory

Implementations

impl LazyFileHandle

pub fn new(file_size: usize, read_fn: RangeReadFn) -> Self

Create a new lazy file handle

pub fn file_size(&self) -> usize

Get file size

pub fn slice(&self, range: Range<usize>) -> LazyFileSlice

Create a sub-slice view (still lazy)
