Trait sodoken::buffer::AsExtendMut

pub trait AsExtendMut<'a>: 'a {
    unsafe fn unsafe_extend_mut(
        &mut self, 
        len: usize
    ) -> SodokenResult<&mut [u8]>;

    fn extend_mut(&mut self, len: usize) -> SodokenResult<&mut [u8]> { ... }
    fn extend_mut_from_slice(&mut self, oth: &[u8]) -> SodokenResult<()> { ... }
}

Indicates we can append bytes without pre-initializing them.

Required methods

unsafe fn unsafe_extend_mut(&mut self, len: usize) -> SodokenResult<&mut [u8]>

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

Provided methods

fn extend_mut(&mut self, len: usize) -> SodokenResult<&mut [u8]>

You probably don’t want this function… it leads to an extra slow initialization step. See unsafe_extend_mut or extend_mut_from_slice.

fn extend_mut_from_slice(&mut self, oth: &[u8]) -> SodokenResult<()>

Extend this extendable buffer with given slice
