Struct ReaderMut 

pub struct ReaderMut<'lt> { /* private fields */ }

A mutable reference to a Reader.

This type acts similar to a very fat mutable reference. It can be obtained by constructing a concrete reader type and calling Reader::as_mut.

Note: Any mutable reference to a Reader implements Into<ReaderMut> for its lifetime. Use this instead of coercion which would be available if this was a builtin kind of reference.

Note: Any Reader implements Into<ReaderBox>, which can again be converted to ReaderMut. Use it for owning a writer without its specific type similar to Box<dyn Write>.

Implementations

impl ReaderMut<'_>

pub fn as_read_mut(&mut self) -> &mut (dyn Read + '_)

Get the inner value as a mutable dynamic Read reference.

impl ReaderMut<'_>

pub fn as_buf(&self) -> Option<&dyn BufRead>

Get the inner value as a dynamic BufRead reference.

This returns None unless a previous call to Reader::set_buf as executed, by any other caller. The value can be moved after such call arbitrarily.

pub fn as_buf_mut(&mut self) -> Option<&mut dyn BufRead>

Get the inner value as a mutable dynamic BufRead reference.

This returns None unless a previous call to Reader::set_buf as executed, by any other caller. The value can be moved after such call arbitrarily.

pub fn as_seek(&self) -> Option<&dyn Seek>

Get the inner value as a dynamic Seek reference.

This returns None unless a previous call to Reader::set_seek as executed, by any other caller. The value can be moved after such call arbitrarily.

pub fn as_seek_mut(&mut self) -> Option<&mut dyn Seek>

Get the inner value as a mutable dynamic Seek reference.

This returns None unless a previous call to Reader::set_seek as executed, by any other caller. The value can be moved after such call arbitrarily.

pub fn as_any(&self) -> Option<&dyn Any>

Get the inner value as a dynamic Any reference.

pub fn as_any_mut(&mut self) -> Option<&mut dyn Any>

Get the inner value as a dynamic Any reference.

impl ReaderMut<'_>

pub fn as_file_ext(&self) -> Option<&dyn FileExt>

Get the inner value as a dynamic FileExt reference.

pub fn as_fd(&self) -> Option<&dyn AsFd>

Get the inner value as a dynamic AsFd reference.

pub fn as_raw_fd(&self) -> Option<&dyn AsRawFd>

Get the inner value as a dynamic AsRawFd reference.
