Enum Annotation 

Source
#[non_exhaustive]
pub enum Annotation { AutoCreateTime, AutoUpdateTime, AutoIncrement, Choices(Vec<String>), DefaultValue(DefaultValue), Index(Option<IndexValue>), MaxLength(i32), NotNull, PrimaryKey, Unique, ForeignKey(ForeignKey), }
Expand description

The subset of annotations which need to be communicated with the migration tool

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

AutoCreateTime

Only for DbType::Timestamp, DbType::DateTime, DbType::Time and DbType::Date. Will set the current time of the database when a row is created.

§

AutoUpdateTime

Only for DbType::Timestamp, DbType::DateTime, DbType::Time and DbType::Date. Will set the current time of the database when a row is updated.

§

AutoIncrement

AUTO_INCREMENT constraint

§

Choices(Vec<String>)

A list of choices to set

§

DefaultValue(DefaultValue)

DEFAULT constraint

§

Index(Option<IndexValue>)

Create an index. The optional IndexValue can be used, to build more complex indexes.

§

MaxLength(i32)

Only for VARCHAR, VARBINARY. Specifies the maximum length of the column’s content.

§

NotNull

NOT NULL constraint

§

PrimaryKey

The annotated column will be used as primary key

§

Unique

UNIQUE constraint

§

ForeignKey(ForeignKey)

Foreign Key constraint

Implementations§

Source

pub fn hash_shallow(&self) -> u64

Alternative shallow hash function.

Returns true on:
