Struct RemoveFieldBuilder

pub struct RemoveFieldBuilder { /* private fields */ }

Available on crate feature db only.

A builder for removing a field from a model.

Typically, you shouldn’t need to use this directly. Instead, in most cases, this can be automatically generated by the Cot CLI.

Examples

use cot::db::migrations::{Field, Operation};
use cot::db::{DatabaseField, Identifier};

const OPERATION: Operation = Operation::remove_field()
    .table_name(Identifier::new("todoapp__my_model"))
    .field(Field::new(
        Identifier::new("name"),
        <String as DatabaseField>::TYPE,
    ))
    .build();

Implementations

pub const fn table_name(self, table_name: Identifier) -> Self
