Struct ColumnModel 

pub struct ColumnModel {
    pub name: String,
    pub kind: ColumnKind,
    pub nullable: bool,
    pub required: bool,
    pub is_primary_key: bool,
    pub filterable: bool,
    pub sortable: bool,
}

One column of a declared table, as the contract’s row schema describes it.

Fields

name: String

The wire key, as the schema spells it.

kind: ColumnKind

The normalized type, from the schema’s type/enum shape.

nullable: bool

Whether the schema says the column can hold null: a type array carrying "null", or an enum listing it.

required: bool

Whether the schema lists the column under required.

is_primary_key: bool

Whether the schema marks the column as the table’s primary key — by a description that begins with the words Primary key of followed by the table’s name, the one way cratefield_tables::json_schema marks it.

filterable: bool

Whether the page’s query accepts an equality filter on the column: every kind but ColumnKind::Opaque.

sortable: bool

Whether the page may be sorted by the column: the schema-required columns and the primary key.
