Struct BytesTapeView 

pub struct BytesTapeView<'a, Offset: OffsetType = i32> { /* private fields */ }

Binary bytes view over RawTapeView.

Implementations

impl<'a, Offset: OffsetType> BytesTapeView<'a, Offset>

pub unsafe fn from_raw_parts(data: &'a [u8], offsets: &'a [Offset]) -> Self

Creates a zero-copy BytesTapeView from raw Arrow BinaryArray parts.

Safety

The caller must ensure that:

• data contains valid bytes for the lifetime 'a
• offsets contains valid offsets with appropriate length
• All offsets are within bounds of the data slice

pub fn get(&self, index: usize) -> Option<&[u8]>

Returns a reference to the bytes at the given index, or None if out of bounds.

pub unsafe fn get_unchecked(&self, index: usize) -> &[u8]

Returns a reference to the bytes at the given index without bounds checking.

Safety

Caller must ensure index < self.len().

pub fn len(&self) -> usize

Returns the number of items in this view.

pub fn is_empty(&self) -> bool

Returns true if the view contains no items.

pub fn data_len(&self) -> usize

Returns the total number of bytes in this view.

pub fn subview( &self, start: usize, end: usize, ) -> Result<BytesTapeView<'a, Offset>, StringTapeError>

Creates a sub-view of this view

pub fn as_raw_parts(&self) -> RawParts<Offset>

Returns the raw parts of the view for Apache Arrow compatibility.

pub fn iter(&'a self) -> BytesTapeViewIter<'a, Offset>

Returns an iterator over the byte slices in this view.

impl<'a, Offset: OffsetType> BytesTapeView<'a, Offset>

pub fn try_into_chars_view( self, ) -> Result<CharsTapeView<'a, Offset>, StringTapeError>

Trait Implementations

impl<'a, Offset: OffsetType> Debug for BytesTapeView<'a, Offset>

Converts to this type from the input type.

impl<'a, Offset: OffsetType> Hash for BytesTapeView<'a, Offset>

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

impl<'a, Offset: OffsetType> Index<usize> for BytesTapeView<'a, Offset>

type Output = [u8]

The returned type after indexing.

fn index(&self, index: usize) -> &Self::Output

Performs the indexing (container[index]) operation.

impl<'a, Offset: OffsetType> IntoIterator for &'a BytesTapeView<'a, Offset>

type Item = &'a [u8]

The type of the elements being iterated over.

type IntoIter = BytesTapeViewIter<'a, Offset>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl<'a, Offset: OffsetType> Ord for BytesTapeView<'a, Offset>

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<'a, Offset: OffsetType> PartialEq for BytesTapeView<'a, Offset>

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
