Struct RawFile 

pub struct RawFile { /* private fields */ }

Use for file size less than 2G If the file size is greater than 2G, there is a risk of precision loss, it is recommended to use RawFile64

Implementations

impl RawFile

pub fn from_raw(raw: *mut RawFile) -> Self

pub fn file_size(&self) -> i32

pub fn seek(&self, offset: i32, whence: i32) -> i32

pub fn offset(&self) -> i32

pub fn read(&self, len: usize) -> Vec<u8>

pub fn remain(&self) -> i32

pub fn fd(&self, start: i32, len: i32) -> i32

try to get fd with start and length get failed it will return -1 and then return fd

fn drop(&mut self)

Executes the destructor for this type.
