A dynamic cell to be appended into a dynamic column builder.

Variants

Null

Append a null to the target column.

Bool(bool)

Boolean value for DataType::Boolean.

I8(i8)

8-bit signed integer for DataType::Int8.

I16(i16)

16-bit signed integer for DataType::Int16.

I32(i32)

32-bit signed integer for DataType::Int32.

I64(i64)

64-bit signed integer for DataType::Int64.

U8(u8)

8-bit unsigned integer for DataType::UInt8.

U16(u16)

16-bit unsigned integer for DataType::UInt16.

U32(u32)

32-bit unsigned integer for DataType::UInt32.

U64(u64)

64-bit unsigned integer for DataType::UInt64.

F32(f32)

32-bit floating point for DataType::Float32.

F64(f64)

64-bit floating point for DataType::Float64.

Str(String)

UTF-8 string for DataType::Utf8 or DataType::LargeUtf8 (and their dictionary forms).

Bin(Vec<u8>)

Arbitrary bytes for DataType::Binary, DataType::LargeBinary, or DataType::FixedSizeBinary(w) (length must equal w) and their dictionary forms.

Struct(Vec<Option<DynCell>>)

Struct cell with one entry per child field (same length as the struct’s fields). Each child may be None (null) or a nested DynCell matching the child’s type.

List(Vec<Option<DynCell>>)

Variable-size list (used for both List and LargeList); items can be null. The child element type must match the list’s item field.

FixedSizeList(Vec<Option<DynCell>>)

Fixed-size list; the number of items must match the list’s declared length. Each item may be None (null) or a nested DynCell matching the child type.

Implementations

impl DynCell

pub fn type_name(&self) -> &'static str

A short, human-readable type name for diagnostics.
