Struct ArrowFieldRef 

pub struct ArrowFieldRef { /* private fields */ }

Reference to an Arrow source field used by a schema mapping.

This is this crate’s mapped source-field metadata. It is not a replacement for arrow_schema::Field.

Implementations

impl ArrowFieldRef

pub const fn new( index: usize, name: String, nullable: bool, data_type: DataType, ) -> Self

Creates an Arrow source field reference.

pub const fn index(&self) -> usize

Returns the Arrow field index.

pub fn name(&self) -> &str

Returns the Arrow field name.

pub const fn nullable(&self) -> bool

Returns true when the Arrow field is nullable.

pub const fn data_type(&self) -> &DataType

Returns the Arrow field data type.

Trait Implementations

impl Clone for ArrowFieldRef

fn clone(&self) -> ArrowFieldRef

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ArrowFieldRef

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

Formats the value using the given formatter.

impl PartialEq for ArrowFieldRef

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