Struct StructTypeInner 

struct StructTypeInner {
    fields: Box<[(String, DataType)]>,
    field_ids: Option<Box<[ColumnId]>>,
    is_unnamed: bool,
}

Fields

fields: Box<[(String, DataType)]>

The name and data type of each field.

If fields are unnamed, the names will be f1, f2, etc.

field_ids: Option<Box<[ColumnId]>>

The ids of the fields. Used in serialization for nested-schema evolution purposes.

Only present if this data type is persisted within a table schema (ColumnDesc) in a new version of the catalog that supports nested-schema evolution.

is_unnamed: bool

Whether the fields are unnamed.

Trait Implementations

impl Clone for StructTypeInner

fn clone(&self) -> StructTypeInner

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StructTypeInner

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

Formats the value using the given formatter.

impl Hash for StructTypeInner

where Box<[(String, DataType)]>: Hash,

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 StructTypeInner

where Box<[(String, DataType)]>: PartialEq,

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
