Struct ColumnType 

pub struct ColumnType {
    pub nullability: Nullability,
    pub data_type: DataType,
}

The relational type of a column or parameter, including nullability. Returned e.g. by crate::Prepared::describe_param.

Fields

nullability: Nullability

Indicates whether the column or parameter may be NULL.

data_type: DataType

The SQL data type of the column or parameter.

Trait Implementations

impl Clone for ColumnType

fn clone(&self) -> ColumnType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ColumnType

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

Formats the value using the given formatter.

impl PartialEq for ColumnType

fn eq(&self, other: &ColumnType) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
