Provides information about a SQL type for the database driver.

Required Methods

fn is_null(&self) -> bool

fn name(&self) -> &str

Returns the database system name of the type. Length specifiers should not be included. Common type names are VARCHAR, TEXT, or INT. Type names should be uppercase. They should be a rough approximation of how they are written in SQL in the given database.

Provided Methods

fn type_compatible(&self, other: &Self) -> bool

where Self: Sized,

Return true if self and other represent mutually compatible types.

Defaults to self == other.
