Trait WritableBytes 

pub trait WritableBytes: Debug {
    // Required methods
    fn len(&self) -> u64;
    fn write_at(
        &mut self,
        offset: u64,
        source: &[u8],
    ) -> Result<(), ByteAccessError>;

    // Provided methods
    fn is_empty(&self) -> bool { ... }
    fn as_contiguous_mut(&mut self) -> Option<&mut [u8]> { ... }
}

Bounded writable bytes exposed by a transport implementation.

Implementations may be segmented. Every operation is nonblocking and allocation-free.

Required Methods

fn len(&self) -> u64

Stable logical byte length.

fn write_at( &mut self, offset: u64, source: &[u8], ) -> Result<(), ByteAccessError>

Write source to the exact logical range beginning at offset.

Provided Methods

fn is_empty(&self) -> bool

Whether this destination contains no bytes.

fn as_contiguous_mut(&mut self) -> Option<&mut [u8]>

Borrow the complete destination when the concrete mapping is contiguous and stable.

Dyn Compatibility

This trait is dyn compatible.

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