Trait Type 

pub trait Type:
    FromSql
    + ToSql
    + Sealed {
    const SQL_TYPE: SqlType;
}

The type of the keys or values that are stored in an SQLiteMap or an SQLiteSet.

Currently, the following types are supported:

Type	SQLite storage datatype
i32	INTEGER
u32	INTEGER
i64	INTEGER
Vec<u8>, alias Blob	BLOB
String	TEXT

 

Type u64 is not currently supported directly, because SQLite’s INTEGER datatype is (at most) 64-Bit in size and is always signed; it can not store values greater than i64::MAX. To store u64 keys or values, please use value as i64 to convert the keys or value to i64 before insertion. This can be reverted, after a key or value has been read, with value as u64.

Required Associated Constants

const SQL_TYPE: SqlType

The SQLite storage datatype that corresponds to this type.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
