Struct scylla_cql::types::deserialize::frame_slice::FrameSlice

pub struct FrameSlice<'frame> { /* private fields */ }

A reference to a part of the frame.

Implementations

impl<'frame> FrameSlice<'frame>

pub fn new(frame: &'frame Bytes) -> Self

Creates a new FrameSlice from a reference of a Bytes object.

This method is exposed to allow writing deserialization tests for custom types.

pub fn new_empty() -> Self

Creates an empty FrameSlice.

pub fn is_empty(&self) -> bool

Returns true if the slice has length of 0.

pub fn as_slice(&self) -> &'frame [u8]

Returns the subslice.

pub fn as_slice_mut(&mut self) -> &mut &'frame [u8]

Returns a mutable reference to the subslice.

pub fn as_original_frame_bytes(&self) -> &'frame Bytes

Returns a reference to the Bytes object which encompasses the whole frame slice.

The Bytes object will usually be larger than the slice returned by FrameSlice::as_slice. If you wish to obtain a new Bytes object that points only to the subslice represented by the FrameSlice object, see FrameSlice::to_bytes.

pub fn to_bytes(&self) -> Bytes

Returns a new Bytes object which is a subslice of the original Bytes frame slice object.
