Enum sqlite::Value

pub enum Value {
    Binary(Vec<u8>),
    Float(f64),
    Integer(i64),
    String(String),
    Null,
}

A value of a specific type.

Variants

Binary(Vec<u8>)

Integer(i64)

An integer number.

String(String)

A string.

Null

A null value.

Implementations

impl Value

pub fn as_binary(&self) -> Option<&[u8]>

Return the binary data if the value is Binary.

pub fn as_float(&self) -> Option<f64>

Return the floating-point number if the value is Float.

pub fn as_integer(&self) -> Option<i64>

Return the integer number if the value is Integer.

pub fn as_string(&self) -> Option<&str>

Return the string if the value is String.

pub fn kind(&self) -> Type

Return the type.

Trait Implementations

impl<'l> Bindable for &'l Value

fn bind(self, statement: &mut Statement<'_>, i: usize) -> Result<()>

Bind to a parameter.

impl Clone for Value

fn clone(&self) -> Value

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Value

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

Formats the value using the given formatter.

impl From<()> for Value

fn from(_: ()) -> Self

Converts to this type from the input type.

impl From<String> for Value

fn from(value: String) -> Self

Converts to this type from the input type.

impl From<Vec<u8, Global>> for Value

fn from(value: Vec<u8>) -> Self

Converts to this type from the input type.

impl From<f64> for Value

fn from(value: f64) -> Self

Converts to this type from the input type.

impl From<i64> for Value

fn from(value: i64) -> Self

Converts to this type from the input type.

impl PartialEq<Value> for Value

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Readable for Value

fn read(statement: &Statement<'_>, i: usize) -> Result<Self>

Read from a column.

impl ValueInto for Value

fn into(value: &Value) -> Option<Self>

impl StructuralPartialEq for Value
