Enum Array

#[non_exhaustive]
pub enum Array {
Show 18 variants Bool(BooleanArray), Int8(PrimitiveArray<i8>), Int16(PrimitiveArray<i16>), Int32(PrimitiveArray<i32>), Int64(PrimitiveArray<i64>), UInt8(PrimitiveArray<u8>), UInt16(PrimitiveArray<u16>), UInt32(PrimitiveArray<u32>), UInt64(PrimitiveArray<u64>), Float32(PrimitiveArray<f32>), Float64(PrimitiveArray<f64>), Decimal(DecimalArray), Timestamp(TimestampArray), Utf8(Utf8Array), Categorical(Utf8Array), Binary(BinaryArray), FixedBinary(BinaryArray), Date32(PrimitiveArray<i32>),

Expand description

A logical column array. Each variant has exactly one value position per row; nullability is carried by the typed array’s validity bitmap.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Implementations§

Source§

impl Array

Source

pub fn len(&self) -> usize

The logical row count.

Source

pub fn is_empty(&self) -> bool

Whether this array has no rows.

Source

pub fn is_null(&self, index: usize) -> bool

Whether the logical position at index is null. A position outside the array is not null; bound the index with len.

Source

pub fn value_at(&self, index: usize) -> Option<ScalarValue<'_>>

Borrow the logical value at a row, or None for a null position.
