Enum Type 

#[repr(i32)]
pub enum Type {
    Integer = 1,
    Float = 2,
    Text = 3,
    Blob = 4,
    Null = 5,
}

The datatype of a SQLite column value.

SQLite uses a dynamic type system. Each value stored in a SQLite database has one of these five types.

Variants

Integer = 1

Float = 2

Text = 3

Blob = 4

Null = 5

Implementations

impl Type

pub const fn has_value(&self) -> bool

true unless this Type is NULL; false for NULL.

pub const fn is_null(&self) -> bool

true if this Type is NULL; false otherwise.

Trait Implementations

impl Clone for Type

fn clone(&self) -> Type

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Type

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

Formats the value using the given formatter.

impl<'r> Fetch<'r> for Type

type Value = Type

fn from_value(value: Self::Value) -> Result<Self>

fn fetch_column<'c>( statement: &'r Statement<'c>, column: ColumnIndex, ) -> Result<Self>

fn fetch_value<'c>(value: &'r ValueRef<'c>) -> Result<Self>

Available on crate features functions or value only.

impl<'r> Fetch<'r> for Type

unsafe fn fetch_column<'c>( statement: &'r Statement<'c>, column: ColumnIndex, ) -> Self

where 'c: 'r,

Fetch a column value from the statement.

unsafe fn fetch_value<'c>(value: &'r ValueRef<'c>) -> Self

where 'c: 'r,

Available on crate features functions or value only.

Unpack a dynamic value into this type.

impl PartialEq for Type

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