pub struct ExtendGuard<'a>(pub Box<dyn AsExtendMut<'a> + 'a, Global>);

An extend guard, indicating we have gained access to extend the buffer.

0: Box<dyn AsExtendMut<'a> + 'a, Global>

Implementations

impl<'a> ExtendGuard<'a>

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>

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>

Extend this extendable buffer with given slice
