Struct aws_sdk_timestreamquery::types::ColumnInfo

#[non_exhaustive]
pub struct ColumnInfo {
    pub name: Option<String>,
    pub type: Option<Box<Type>>,
}

Contains the metadata for query results such as the column names, data types, and other attributes.

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>

The name of the result set column. The name of the result set is available for columns of all data types except for arrays.

type: Option<Box<Type>>

The data type of the result set column. The data type can be a scalar or complex. Scalar data types are integers, strings, doubles, Booleans, and others. Complex data types are types such as arrays, rows, and others.

Implementations

impl ColumnInfo

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

The name of the result set column. The name of the result set is available for columns of all data types except for arrays.

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

The data type of the result set column. The data type can be a scalar or complex. Scalar data types are integers, strings, doubles, Booleans, and others. Complex data types are types such as arrays, rows, and others.

impl ColumnInfo

pub fn builder() -> ColumnInfoBuilder

Creates a new builder-style object to manufacture ColumnInfo.

Trait Implementations

impl Clone for ColumnInfo

fn clone(&self) -> ColumnInfo

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ColumnInfo

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

Formats the value using the given formatter.

impl PartialEq<ColumnInfo> for ColumnInfo

fn eq(&self, other: &ColumnInfo) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
