Struct FillRequired 

pub struct FillRequired {
    pub module: String,
    pub table: String,
    pub column: String,
    pub pg_type: String,
    pub type_name: String,
    pub is_new_column: bool,
    pub default_sql: Option<String>,
}

A column that is being made NOT NULL but currently contains (or could contain) NULL rows, requiring a fill expression to backfill existing rows before the constraint can be added.

Fields

module: String

Schema / Postgres schema name of the table.

table: String

column: String

pg_type: String

type_name: String

Python-level type name — used in the prompt (“property ‘x’ of ‘Post’”).

is_new_column: bool

True when the column doesn’t exist yet (ADD COLUMN); false when it already exists as nullable (nullability change).

default_sql: Option<String>

The schema-level default= SQL, if one is declared. When present it can be used as an automatic fill expression without prompting the user.
