}

A column in a table.

Fields

name: String

The column name.

ordinal_position: u32

The 1-based position of the column in the table definition.

data_type: String

The SQL data type name as reported by the backend.

nullable: bool

Whether the column accepts NULL values.

default: Option<String>

The column default expression, if any.

max_length: Option<u64>

numeric_precision: Option<u32>

Numeric precision, if applicable.

numeric_scale: Option<u32>

Numeric scale, if applicable.

Trait Implementations

impl Clone for ColumnInfo

fn clone(&self) -> ColumnInfo

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ColumnInfo

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

Formats the value using the given formatter.

impl Eq for ColumnInfo

impl PartialEq for ColumnInfo

fn eq(&self, other: &ColumnInfo) -> 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.
