Struct FixedBinary 

pub struct FixedBinary<const N: usize>(pub [u8; N]);

FixedSizeBinary(N) wire type carried as [u8; N]. The const generic encodes the width so the schema is fully determined.

Tuple Fields

0: [u8; N]

Trait Implementations

impl<const N: usize> Clone for FixedBinary<N>

fn clone(&self) -> FixedBinary<N>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<const N: usize> Debug for FixedBinary<N>

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

Formats the value using the given formatter.

impl<const N: usize> Eq for FixedBinary<N>

impl<const N: usize> From<[u8; N]> for FixedBinary<N>

fn from(b: [u8; N]) -> Self

Converts to this type from the input type.

impl<const N: usize> PartialEq for FixedBinary<N>

fn eq(&self, other: &FixedBinary<N>) -> 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<const N: usize> StructuralPartialEq for FixedBinary<N>

impl<const N: usize> VgiArrow for FixedBinary<N>

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.
