Trait Implementations

impl Clone for Value

fn clone(&self) -> Value

Returns a duplicate 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 Display for Value

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

Formats the value using the given formatter.

impl From<bool> for Value

fn from(v: bool) -> Self

Converts to this type from the input type.

impl From<f64> for Value

fn from(v: f64) -> Self

Converts to this type from the input type.

impl From<i64> for Value

fn from(v: i64) -> Self

Converts to this type from the input type.

impl From<u32> for Value

fn from(v: u32) -> Self

Converts to this type from the input type.

impl From<u64> for Value

fn from(v: u64) -> Self

Converts to this type from the input type.

impl FromBytes for Value

fn from_bytes<R: Read>(bytes: &mut R) -> Result<Self>

where Self: Sized,

impl FromText for Value

fn from_text(text: &str) -> Result<Self>

where Self: Sized,

impl PartialEq for Value

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

type Error = Report

The type returned in the event of a conversion error.

fn try_from(v: Value) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<Value> for f64

type Error = Report

The type returned in the event of a conversion error.

fn try_from(v: Value) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<Value> for i64

type Error = Report

The type returned in the event of a conversion error.

fn try_from(v: Value) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<Value> for u32

type Error = Report

The type returned in the event of a conversion error.

fn try_from(v: Value) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<Value> for u64

type Error = Report

The type returned in the event of a conversion error.

fn try_from(v: Value) -> Result<Self, Self::Error>

Performs the conversion.

impl WriteBytes for Value
