Trait Implementations

impl<'a> Clone for ColumnData<'a>

fn clone(&self) -> ColumnData<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for ColumnData<'a>

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

Formats the value using the given formatter.

impl<'de, 'a> Deserialize<'de> for ColumnData<'a>

Available on crate feature serde only.

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'a> FromSql<'a> for ColumnData<'a>

Reads a ColumnData straight out of a row without any conversion, borrowing from the row’s owned data.

fn from_sql(value: &'a ColumnData<'static>) -> Result<Option<Self>>

Returns the value, None being a null value, copying the value.

impl<'a> FromSqlOwned for ColumnData<'a>

Reads a ColumnData straight out of a row without any conversion, taking ownership of the value.

fn from_sql_owned(value: ColumnData<'static>) -> Result<Option<Self>>

Returns the value, None being a null value, taking the ownership.

impl<'a> IntoSql<'a> for ColumnData<'a>

Binds a ColumnData directly as a query parameter, by value.

fn into_sql(self) -> ColumnData<'a>

Convert to a value understood by the SQL Server. Conversion by-value.

impl<'a> PartialEq for ColumnData<'a>

fn eq(&self, other: &ColumnData<'a>) -> bool

Equality operator ==.

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

Inequality operator !=.

impl<'a> Serialize for ColumnData<'a>

Available on crate feature serde only.

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<'a> StructuralPartialEq for ColumnData<'a>

impl<'a> ToSql for ColumnData<'a>
