pub struct TakeSeek<T> { /* private fields */ }
Expand description
Read adapter which limits the bytes read from an underlying reader, with seek support.
This struct is generally created by importing the TakeSeekExt
extension
and calling take_seek
on a reader.
Implementations§
source§impl<T> TakeSeek<T>
impl<T> TakeSeek<T>
sourcepub fn get_mut(&mut self) -> &mut T
pub fn get_mut(&mut self) -> &mut T
Gets a mutable reference to the underlying reader.
Care should be taken to avoid modifying the internal I/O state of the
underlying reader as doing so may corrupt the internal limit of this
TakeSeek
.
sourcepub fn into_inner(self) -> T
pub fn into_inner(self) -> T
Consumes this wrapper, returning the wrapped value.
