Struct Field 

pub struct Field {
    pub name: String,
    pub ty: LogicalType,
    pub not_null: bool,
}

A named field of a STRUCT or a UNION, and a named column of a table.

Fields

name: String

The field name, unquoted and case sensitive as stored.

ty: LogicalType

The field type.

not_null: bool

Whether the column refuses nulls, which is the NOT NULL the DDL declared it with.

Always false inside a STRUCT or a UNION, because a null is a property of a value at every nesting level and no type in SQL says a value cannot be one. This is here rather than on a separate column type because a table column is already spelled with this struct, and a second one that was this one plus a flag would have to be threaded through the binder, the scope and every operator schema to carry a bit that only the insert path reads.

Implementations

impl Field

pub fn new(name: impl Into<String>, ty: LogicalType) -> Self

A field with a name and a type, which accepts nulls.

pub fn required(name: impl Into<String>, ty: LogicalType) -> Self

A column with a name and a type, which refuses nulls.
