Enum ColumnType 

#[repr(C)]
pub enum ColumnType {
    Boolean = 0,
    Varchar = 1,
    Double = 2,
    Integer = 3,
    Geometry = 4,
}

Logical column types used by GeoPackage layers and DDL helpers.

Variants

Boolean = 0

Boolean value stored as an integer 0/1.

Varchar = 1

UTF-8 text column.

Double = 2

Floating point column (SQLite REAL).

Integer = 3

Integer column (SQLite INTEGER).

Geometry = 4

Geometry column stored as a GeoPackage BLOB.

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.

impl Copy for ColumnType
