Struct Schema 

pub struct Schema { /* private fields */ }

Schema with a bimap to allow easy name <-> index retrieval

Implementations

impl Schema

pub fn new( column_data_types: Vec<DataType>, column_name_to_index: BiMap<String, usize>, ) -> Self

pub fn get_column_count(&self) -> usize

Returns how many columns in the Table

pub fn get_column_name(&self, column_index: usize) -> Result<&str>

Returns column name given a column index

pub fn get_column_index(&self, column_name: &str) -> Result<usize>

Returns column index given a column name

pub fn get_column_data_type(&self, column_index: usize) -> Result<DataType>

Returns column data type given a column index

pub fn get_column_data_type_by_name( &self, column_name: &str, ) -> Result<DataType>

Returns column data type given a column index

pub fn get_colum_data_types(&self) -> &[DataType]

Returns column data types

pub fn get_column_name_to_index_map(&self) -> &BiMap<String, usize>

Returns column data types

pub fn into_data_types_and_name_to_index_map( self, ) -> (Vec<DataType>, BiMap<String, usize>)

Trait Implementations

impl Clone for Schema

fn clone(&self) -> Schema

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Schema

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Schema

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Schema

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

impl Serialize for Schema

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Schema
