pub struct Blueprint { /* private fields */ }

The columns, indexes and foreign keys of a table, in the order they were added.

Implementations

impl Blueprint

pub fn id(&mut self) -> &mut Column

An auto-incrementing 64-bit primary key named id.

pub fn string(&mut self, name: &str) -> &mut Column

A VARCHAR(255); TEXT on SQLite. Change the length with .length(n).

pub fn text(&mut self, name: &str) -> &mut Column

A TEXT column.

pub fn integer(&mut self, name: &str) -> &mut Column

An INTEGER column.

pub fn big_integer(&mut self, name: &str) -> &mut Column

A BIGINT column; INTEGER on SQLite, whose integers are 64-bit already.

pub fn boolean(&mut self, name: &str) -> &mut Column

A boolean: BOOLEAN on PostgreSQL, TINYINT(1) elsewhere.

pub fn date_time(&mut self, name: &str) -> &mut Column

A date and time without a time zone: DATETIME, or TIMESTAMP(0) on PostgreSQL.

pub fn timestamps(&mut self)

Nullable created_at and updated_at columns.

pub fn unique<I, S>(&mut self, columns: I)

where I: IntoIterator<Item = S>, S: AsRef<str>,

A unique constraint over columns, named {table}_{columns}_unique.

pub fn index<I, S>(&mut self, columns: I)

where I: IntoIterator<Item = S>, S: AsRef<str>,

A plain index over columns, named {table}_{columns}_index.

pub fn foreign(&mut self, column: &str) -> &mut ForeignKey

A foreign key on column, named {table}_{column}_foreign.
