Implementations

impl SqlVal

pub fn as_ref(&self) -> SqlValRef<'_>

pub fn bool(&self) -> Result<bool>

pub fn integer(&self) -> Result<i32>

pub fn bigint(&self) -> Result<i64>

pub fn real(&self) -> Result<f64>

pub fn text(&self) -> Result<&str>

pub fn owned_text(self) -> Result<String>

pub fn blob(&self) -> Result<&[u8]>

pub fn owned_blob(self) -> Result<Vec<u8>>

pub fn is_compatible(&self, t: &SqlType, null_allowed: bool) -> bool

Tests if this sqlval is compatible with the given SqlType. There are no implicit type conversions (i.e. if this is a SqlVal::Bool, it is only compatible with SqlType::Bool, not with SqlType::Int, even though an int contains enough information to encode a bool.

pub fn sqltype(&self) -> Option<SqlType>

Trait Implementations

impl Clone for SqlVal

fn clone(&self) -> SqlVal

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SqlVal

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SqlVal

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for SqlVal

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

Formats the value using the given formatter.

impl<'a> From<&'a SqlVal> for SqlValRef<'a>

fn from(val: &'a SqlVal) -> SqlValRef<'a>

Converts to this type from the input type.

impl From<SqlValRef<'_>> for SqlVal

fn from(valref: SqlValRef<'_>) -> SqlVal

Converts to this type from the input type.

impl<T> From<T> for SqlValwhere T: ToSql,

fn from(val: T) -> Self

Converts to this type from the input type.

impl PartialEq<SqlVal> for SqlVal

fn eq(&self, other: &SqlVal) -> 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 Serialize for SqlVal

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

Serialize this value into the given Serde serializer.
