Trait MaybeContiguousBuffer 

Source 
pub trait MaybeContiguousBuffer {
    // Required method
    fn linearized<'a, 'b>(
        &'a mut self,
        storage: Option<&'b mut Vec<u8>>,
    ) -> Option<BufferSlice<'a, 'b>>;

    // Provided method
    fn unwrap_contiguous<'a>(&'a mut self) -> &'a mut [u8] ⓘ { ... }
}
Expand description

A buffer that may be backed by a contiguous memory slice.

Required Methods§

Source

fn linearized<'a, 'b>( &'a mut self, storage: Option<&'b mut Vec<u8>>, ) -> Option<BufferSlice<'a, 'b>>

Obtains a slice view into the buffer, linearizing into storage if necessary, or returning None if linearization was required and storage was None.

Provided Methods§

Source

fn unwrap_contiguous<'a>(&'a mut self) -> &'a mut [u8] ⓘ

Obtains a mutable slice into the buffer without linearizing. Panics if called on a buffer that’s not contiguous.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
