Enum barrel::Type

pub enum Type {
    Text,
    Varchar(usize),
    Primary,
    Integer,
    Float,
    Double,
    Boolean,
    Binary,

    Array(Box<Type>),
}

Type enum to specificy the type of an SQL column. NOTE: Not all types are supported by all database backends!

When creating a column users need to specify the type and potential metadata this type requires to the add_column function.

t.add_column("posts", Type::Array(box Type::Foreign("posts")));

Variants

Text

Create a simple "text" field

Varchar(usize)

Provide a size limit for this field

Primary

Create a primary key regardless of database

This type is more of a convenience wrapper around other (64-bit) integer types. It might be changed at some point or just removed.

Be careful when using this type!

Integer

Creates a 64-bit integer

Float

Creates a 32-bit float

Double

Creates a 64-bit float

Boolean

Boring ol' boolean

Binary

Create a simple "binary" field

Foreign(&'static str)

Provide the name of a table to point to

Custom(&'static str)

Used for types not Implemented by the migration system. This field is not statically checked.

Array(Box<Type>)

Any type can also exist as an array type

Trait Implementations

impl PartialEq for Type

fn eq(&self, __arg_0: &Type) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, __arg_0: &Type) -> bool

This method tests for !=.

impl Debug for Type

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Clone for Type

fn clone(&self) -> Type

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
