Associated Types
Loading content...Required methods
fn as_ref(&self) -> <Self::Database as HasValueRef<'_>>::ValueRef
Get this value as a reference.
fn type_info(&self) -> Cow<'_, <Self::Database as Database>::TypeInfo>
Get the type information for this value.
fn is_null(&self) -> bool
Returns true
if the SQL value is NULL
.
Provided methods
fn decode<'r, T>(&'r self) -> T where
T: Decode<'r, Self::Database> + Type<Self::Database>,
T: Decode<'r, Self::Database> + Type<Self::Database>,
Decode this single value into the requested type.
Panics
Panics if the value cannot be decoded into the requested type.
See try_decode
for a non-panicking version.
fn decode_unchecked<'r, T>(&'r self) -> T where
T: Decode<'r, Self::Database>,
T: Decode<'r, Self::Database>,
Decode this single value into the requested type.
Unlike decode
, this method does not check that the type of this
value is compatible with the Rust type and blindly tries to decode the value.
Panics
Panics if the value cannot be decoded into the requested type.
See try_decode_unchecked
for a non-panicking version.
fn try_decode<'r, T>(&'r self) -> Result<T, Error> where
T: Decode<'r, Self::Database> + Type<Self::Database>,
T: Decode<'r, Self::Database> + Type<Self::Database>,
Decode this single value into the requested type.
Errors
Decode
if the value could not be decoded into the requested type.
fn try_decode_unchecked<'r, T>(&'r self) -> Result<T, Error> where
T: Decode<'r, Self::Database>,
T: Decode<'r, Self::Database>,
Decode this single value into the requested type.
Unlike try_decode
, this method does not check that the type of this
value is compatible with the Rust type and blindly tries to decode the value.
Errors
Decode
if the value could not be decoded into the requested type.
