source · pub struct ExtendGuard<'a>(pub Box<dyn AsExtendMut<'a>>);
Expand description
An extend guard, indicating we have gained access to extend the buffer.

Implementations§
source§impl<'a> ExtendGuard<'a>
impl<'a> ExtendGuard<'a>
sourcepub unsafe fn unsafe_extend_mut(
&mut self,
len: usize,
) -> Result<&mut [u8], OneErr>
pub unsafe fn unsafe_extend_mut( &mut self, len: usize, ) -> Result<&mut [u8], OneErr>
§Safety
this is unsafe because the process could potentially
- read uninitialized data from the returned slice
- or fail to initialize the data in the returned slice
