}Expand description
Trait for types that can provide a readonly byte buffer interface to I/O frameworks.
§Safety
The type must support contiguous raw memory access via pointer, such as Vec or [u8].
Required Methods§
Sourcefn bytes_init(&self) -> usize
fn bytes_init(&self) -> usize
Number of initialized bytes.
Provided Methods§
Sourcefn slice_owned(self, range: Range<usize>) -> OwnedSlice<Self>where
Self: Sized,
fn slice_owned(self, range: Range<usize>) -> OwnedSlice<Self>where
Self: Sized,
Access the buffer as a byte slice with begin and end indices
Dyn Compatibility§
This trait is dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety".
