Implementations

impl SqlValue

pub fn type_tag(&self) -> u8

Returns the type tag for serialization (see design type tags).

pub fn is_null(&self) -> bool

Returns true if the value is Null.

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

Human-readable type name for error reporting.

pub fn resolved_type(&self) -> ResolvedType

Returns the corresponding ResolvedType for this value.

Trait Implementations

impl Clone for SqlValue

fn clone(&self) -> SqlValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SqlValue

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SqlValue

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<&[u8]> for SqlValue

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

Converts to this type from the input type.

impl From<&str> for SqlValue

fn from(value: &str) -> Self

Converts to this type from the input type.

impl From<String> for SqlValue

fn from(value: String) -> Self

Converts to this type from the input type.

impl PartialEq for SqlValue

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

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for SqlValue

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,
