Struct Column 

pub struct Column {
    pub name: String,
    pub type_text: String,
    pub type_json: String,
    pub position: Option<i32>,
    pub type_name: ColumnTypeName,
    pub comment: Option<String>,
    pub nullable: Option<bool>,
    pub partition_index: Option<i32>,
}

A Unity Catalog column, the portable shape exchanged with the backend port.

This is the subset of the UC Column message the managed-table contract produces and consumes. The backend adapter maps between this and its own column representation.

Fields

name: String

Name of the column.

type_text: String

Full data type specification as SQL / catalog-string text.

type_json: String

Full data type specification, JSON-serialized (the original Delta type).

position: Option<i32>

Ordinal position of the column (starting at 0).

type_name: ColumnTypeName

Data type name.

comment: Option<String>

User-provided free-form description.

nullable: Option<bool>

Whether the field may be null.

partition_index: Option<i32>

Partition index for the column, if it is a partition column.
