[−][src]Struct arrow::buffer::Buffer
Buffer is a contiguous memory region of fixed size and is aligned at a 64-byte boundary. Buffer is immutable.
Methods
impl Buffer
[src]
impl Buffer
pub fn from_raw_parts(ptr: *const u8, len: usize) -> Self
[src]
pub fn from_raw_parts(ptr: *const u8, len: usize) -> Self
Creates a buffer from an existing memory region (must already be byte-aligned)
pub fn len(&self) -> usize
[src]
pub fn len(&self) -> usize
Returns the number of bytes in the buffer
pub fn is_empty(&self) -> bool
[src]
pub fn is_empty(&self) -> bool
Returns whether the buffer is empty.
pub fn data(&self) -> &[u8]
[src]
pub fn data(&self) -> &[u8]
Returns the byte slice stored in this buffer
pub fn slice(&self, offset: usize) -> Self
[src]
pub fn slice(&self, offset: usize) -> Self
Returns a slice of this buffer, starting from offset
.
pub fn raw_data(&self) -> *const u8
[src]
pub fn raw_data(&self) -> *const u8
Returns a raw pointer for this buffer.
Note that this should be used cautiously, and the returned pointer should not be stored anywhere, to avoid dangling pointers.
pub fn empty() -> Self
[src]
pub fn empty() -> Self
Returns an empty buffer.
