Struct QueryTableRequestColumns 

pub struct QueryTableRequestColumns {
    pub column_names: Option<Vec<String>>,
    pub column_aliases: Option<HashMap<String, String>>,
}

QueryTableRequestColumns : Optional field paths to return. Provide either column_names or column_aliases, not both.

Fields

column_names: Option<Vec<String>>

List of Lance field paths to return. Nested fields use dot-separated segments; use backtick-quoted segments for literal dots and double backticks inside quoted segments.

column_aliases: Option<HashMap<String, String>>

Object mapping output aliases to source Lance field paths. Nested fields use dot-separated segments; use backtick-quoted segments for literal dots and double backticks inside quoted segments.

Implementations

impl QueryTableRequestColumns

pub fn new() -> QueryTableRequestColumns

Optional field paths to return. Provide either column_names or column_aliases, not both.

Trait Implementations

impl Clone for QueryTableRequestColumns

fn clone(&self) -> QueryTableRequestColumns

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QueryTableRequestColumns

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

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for QueryTableRequestColumns

fn deserialize<__D>( __deserializer: __D, ) -> Result<QueryTableRequestColumns, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for QueryTableRequestColumns

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