A yet-to-be-resolved [arrow2::datatypes::DataType].

Type resolution is a two-pass process as we first need to register all existing types before we can denormalize their definitions into their parents.

Implementations

impl LazyDatatype

fn resolve(&self, registry: &ArrowRegistry) -> DataType

Recursively resolves the datatype using the specified registry.

Trait Implementations

impl Clone for LazyDatatype

fn clone(&self) -> LazyDatatype

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LazyDatatype

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

Formats the value using the given formatter.

impl From<DataType> for LazyDatatype

fn from(datatype: DataType) -> Self

Converts to this type from the input type.

impl Hash for LazyDatatype

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for LazyDatatype

fn eq(&self, other: &LazyDatatype) -> 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 Eq for LazyDatatype
