Enum TypeSupport 

pub enum TypeSupport {
    Native(&'static str),
    Emulated(&'static str),
    Degraded(&'static str, &'static str),
    Unsupported,
}

How well a target database supports a canonical type.

Variants

Native(&'static str)

Full native support; DDL string is the type to use in CREATE TABLE.

Emulated(&'static str)

No native type but semantically equivalent storage exists. Package still installs cleanly.

Degraded(&'static str, &'static str)

Type exists but a feature is lost on this database (e.g. JSON indexing).

Unsupported

The type cannot be supported on this database at all.
