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

Implementations
impl<'a> ExtendGuard<'a>
impl<'a> ExtendGuard<'a>
pub 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
pub fn extend_mut(&mut self, len: usize) -> Result<&mut [u8], OneErr>
pub fn extend_mut(&mut self, len: usize) -> Result<&mut [u8], OneErr>
You probably don’t want this function… it leads to
an extra slow initialization step.
See unsafe_extend_mut
or extend_mut_from_slice
.
pub fn extend_mut_from_slice(&mut self, oth: &[u8]) -> Result<(), OneErr>
pub fn extend_mut_from_slice(&mut self, oth: &[u8]) -> Result<(), OneErr>
Extend this extendable buffer with given slice
