Struct Nullability 

pub struct Nullability {
    pub inner: bool,
    pub outer: bool,
}

The nullability of a nested arrow datatype.

Fields

inner: bool

The inner datatype is nullable (e.g. for a list array, one row’s array may contain nulls).

outer: bool

The outer datatype is nullable (e.g, the a list array, one row may have a null instead of an array).

Implementations

impl Nullability

pub const NONE: Self

pub const BOTH: Self

pub const INNER: Self

pub const OUTER: Self

pub const ALL: &'static [Self]

pub fn from_field(field: &Field) -> Self

pub fn is_either(&self) -> bool

Trait Implementations

impl Clone for Nullability

fn clone(&self) -> Nullability

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Nullability

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

Formats the value using the given formatter.

impl PartialEq for Nullability

fn eq(&self, other: &Nullability) -> 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.
