Struct Annotations 

pub struct Annotations {
    pub auto_create_time: bool,
    pub auto_update_time: bool,
    pub auto_increment: bool,
    pub choices: bool,
    pub default: bool,
    pub index: bool,
    pub max_length: bool,
    pub not_null: bool,
    pub primary_key: bool,
    pub unique: bool,
    pub foreign_key: bool,
}

Simple struct storing whether a specific annotation is set on a given field or not.

Fields

auto_create_time: bool

Does the field have the Annotation::AutoCreateTime?

auto_update_time: bool

Does the field have the Annotation::AutoUpdateTime?

auto_increment: bool

Does the field have the Annotation::AutoIncrement?

choices: bool

Does the field have the Annotation::Choices?

default: bool

Does the field have the Annotation::DefaultValue?

index: bool

Does the field have an Annotation::Index without a name?

A named index may span several columns, which makes it valid on columns where a single column index wouldn’t be, most notably a primary key. Since this struct can’t express which columns an index spans, named indexes are not tracked here at all.

max_length: bool

Does the field have the Annotation::MaxLength?

not_null: bool

Does the field have the Annotation::NotNull?

primary_key: bool

Does the field have the Annotation::PrimaryKey?

unique: bool

Does the field have the Annotation::Unique?

foreign_key: bool

Does the field have the Annotation::ForeignKey?

Implementations

impl Annotations

pub const fn check(self) -> Result<(), &'static str>

Check whether this set of annotations is valid.

Returns a non-empty error message, when it is not.

Trait Implementations

impl Clone for Annotations

fn clone(&self) -> Annotations

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Annotations

impl Debug for Annotations

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Annotations

fn default() -> Annotations

Returns the “default value” for a type.

impl From<&[Annotation]> for Annotations

fn from(annotations: &[Annotation]) -> Self

Converts to this type from the input type.
