Struct SelectColumn

#[non_exhaustive]
pub struct SelectColumn {
    pub name: Option<String>,
    pub type: Option<Type>,
    pub database_name: Option<String>,
    pub table_name: Option<String>,
    pub aliased: Option<bool>,
}

Details of the column that is returned by the query.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

name: Option<String>

Name of the column.

type: Option<Type>

Contains the data type of a column in a query result set. The data type can be scalar or complex. The supported scalar data types are integers, Boolean, string, double, timestamp, date, time, and intervals. The supported complex data types are arrays, rows, and timeseries.

database_name: Option<String>

Database that has this column.

table_name: Option<String>

Table within the database that has this column.

aliased: Option<bool>

True, if the column name was aliased by the query. False otherwise.

Implementations

impl SelectColumn

pub fn name(&self) -> Option<&str>

Name of the column.

pub fn type(&self) -> Option<&Type>

Contains the data type of a column in a query result set. The data type can be scalar or complex. The supported scalar data types are integers, Boolean, string, double, timestamp, date, time, and intervals. The supported complex data types are arrays, rows, and timeseries.

pub fn database_name(&self) -> Option<&str>

Database that has this column.

pub fn table_name(&self) -> Option<&str>

Table within the database that has this column.

pub fn aliased(&self) -> Option<bool>

True, if the column name was aliased by the query. False otherwise.

impl SelectColumn

pub fn builder() -> SelectColumnBuilder

Creates a new builder-style object to manufacture SelectColumn.

Trait Implementations

impl Clone for SelectColumn

fn clone(&self) -> SelectColumn

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SelectColumn

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

Formats the value using the given formatter.

impl PartialEq for SelectColumn

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