Implementations

impl Value

pub fn kind(&self) -> Type

Return the type.

pub fn try_into<'l, T>(&'l self) -> Result<T>where
    T: TryFrom<&'l Value, Error = Error>,

Try to return the value.

Trait Implementations

impl BindableWithIndex for &Value

fn bind<T: ParameterIndex>(
    self,
    statement: &mut Statement,
    index: T
) -> Result<()>

Bind to a parameter.

impl BindableWithIndex for Value

fn bind<T: ParameterIndex>(
    self,
    statement: &mut Statement,
    index: T
) -> 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<&[u8]> for Value

fn from(value: &[u8]) -> Self

Converts to this type from the input type.

impl From<&str> for Value

fn from(value: &str) -> Self

Converts to this type from the input type.

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.
