pub struct TypedValueScalar { /* private fields */ }Expand description
Represents an Arrow scalar with a TypedValueEncoding.
Implementations§
Source§impl TypedValueScalar
impl TypedValueScalar
Sourcepub fn try_new(value: ScalarValue) -> Result<TypedValueScalar, DataFusionError>
pub fn try_new(value: ScalarValue) -> Result<TypedValueScalar, DataFusionError>
Tries to create a new TypedValueScalar from a regular ScalarValue.
§Errors
Returns an error if the data type of value is unexpected.
Sourcepub fn new_unchecked(inner: ScalarValue) -> TypedValueScalar
pub fn new_unchecked(inner: ScalarValue) -> TypedValueScalar
Creates a new TypedValueScalar without checking invariants.
