Struct Bytes 

pub struct Bytes(pub Vec<u8>);

Newtype indicating a Vec<u8> should be carried as Arrow Binary, not List<UInt8>. Use this in handler signatures where the wire type should be bytes rather than a list of bytes.

#[derive(VgiArrow)] does not auto-pick between the two — there is no idiomatic Rust signal that Vec<u8> in a struct field means “blob” rather than “byte list”, so users opt in via this wrapper.

Tuple Fields

0: Vec<u8>

Trait Implementations

impl Clone for Bytes

fn clone(&self) -> Bytes

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Bytes

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for Bytes

impl From<Bytes> for Vec<u8>

fn from(b: Bytes) -> Self

Converts to this type from the input type.

impl From<Vec<u8>> for Bytes

fn from(v: Vec<u8>) -> Self

Converts to this type from the input type.

impl PartialEq for Bytes

fn eq(&self, other: &Bytes) -> 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.

impl StructuralPartialEq for Bytes

impl VgiArrow for Bytes

fn arrow_data_type() -> DataType

The Arrow DataType carrying values of this Rust type.

fn describe_name() -> String

Wire-format type name surfaced via __describe__ metadata. Mirrors Python: "str", "int", "list[int]", "int | None".

fn read(arr: &dyn Array, idx: usize) -> Result<Self>

Pull this value out of arr at row idx. Errors with a RpcError::type_error if arr’s concrete type doesn’t match Self::arrow_data_type().

fn build_singleton(value: Self) -> Result<ArrayRef>

Build a 1-row ArrayRef containing value.

fn nullable() -> bool

Whether the column should be flagged nullable. The default is false; the Option<T> blanket impl returns true.
