Enum FieldType 

pub enum FieldType {
    Integer,
    Real,
    Text,
    Blob,
    Boolean,
    Date,
    DateTime,
    Null,
}

Column type categories used in GeoPackage / SQLite schemas.

Variants

Integer

Signed integer (SQLite INTEGER affinity).

Real

IEEE-754 double (SQLite REAL affinity).

Text

UTF-8 text (SQLite TEXT affinity).

Blob

Raw binary (SQLite BLOB affinity).

Boolean

Boolean stored as INTEGER 0/1.

Date

Calendar date stored as TEXT "YYYY-MM-DD".

DateTime

Date+time stored as TEXT "YYYY-MM-DDTHH:MM:SS.sssZ".

Null

SQL NULL / unknown type.

Implementations

impl FieldType

pub fn from_sql_type(type_str: &str) -> Self

Derive a FieldType from a SQLite type-name string (case-insensitive).

Unrecognised strings map to FieldType::Text following SQLite type affinity rules.

pub fn as_str(self) -> &'static str

Return the canonical SQL type name string for this field type.

Trait Implementations

impl Clone for FieldType

fn clone(&self) -> FieldType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FieldType

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

Formats the value using the given formatter.

impl Hash for FieldType

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for FieldType

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