Implementations

impl BinaryView

pub const MAX_INLINED_SIZE: usize = 12usize

pub fn make_view(value: &[u8], block: u32, offset: u32) -> Self

Create a view from a value, block and offset

Depending on the length of the provided value either a new inlined or a reference view will be constructed.

Adapted from arrow-rs https://github.com/apache/arrow-rs/blob/f4fde769ab6e1a9b75f890b7f8b47bc22800830b/arrow-array/src/builder/generic_bytes_view_builder.rs#L524 Explicitly enumerating inlined view produces code that avoids calling generic ptr::copy_non_interleave that’s slower than explicit stores

pub fn empty_view() -> Self

Create a new empty view

pub fn new_inlined(value: &[u8]) -> Self

Create a new inlined binary view

pub fn len(&self) -> u32

pub fn is_empty(&self) -> bool

pub fn is_inlined(&self) -> bool

pub fn as_inlined(&self) -> &Inlined

pub fn as_view(&self) -> &Ref

pub fn as_u128(&self) -> u128

pub fn with_buffer_idx(self, buffer_idx: u32) -> Self

Override the buffer reference with the given buffer_idx, only if this view is not inlined.

pub fn offset_view(self, offset: u32) -> Self

Shifts the buffer reference by the view by a given offset, useful when merging many varbinview arrays into one.
