Methods Documentation

async close() → None

async read(size: int = -1) → bytes

Read up to size bytes from the file, or all content if -1

async read_range(offset: int, len: int) → bytes

Read len bytes from the file starting at offset. Doesn’t affect the position in the file

read_range_stream(offset: int, len: int) → AsyncIterator[bytes]

Read len bytes from the file starting at offset as an iterator of bytes. Doesn’t affect the position in the file.

This is the most efficient way to iteratively read a file.

readable() → bool

async readall() → bytes

seek(offset: int, whence=0)

Seek to offset relative to whence

seekable()

tell() → int
