Struct PartitionColumn 

pub struct PartitionColumn {
    pub name: String,
    pub data_type: DataType,
    pub nullable: bool,
}

Partition column materialized from frontend file metadata.

Partition columns are synthetic source columns: they are not present in the Parquet file schema, but they may be read, projected, or used by filters as if they came from the source.

Fields

name: String

Column name exposed to native expressions.

data_type: DataType

Arrow type of the partition value.

nullable: bool

Whether the partition value may be null.

Implementations

impl PartitionColumn

pub fn new(name: impl Into<String>, data_type: DataType, nullable: bool) -> Self

Declares a synthetic partition column with its exposed Arrow type and nullability.
