Struct aws_sdk_rdsdata::types::ResultSetMetadata

#[non_exhaustive]
pub struct ResultSetMetadata {
    pub column_count: i64,
    pub column_metadata: Option<Vec<ColumnMetadata>>,
}

The metadata of the result set returned by a SQL statement.

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.

column_count: i64

The number of columns in the result set.

column_metadata: Option<Vec<ColumnMetadata>>

The metadata of the columns in the result set.

Implementations

impl ResultSetMetadata

pub fn column_count(&self) -> i64

The number of columns in the result set.

pub fn column_metadata(&self) -> &[ColumnMetadata]

The metadata of the columns in the result set.

If no value was sent for this field, a default will be set. If you want to determine if no value was sent, use .column_metadata.is_none().

impl ResultSetMetadata

pub fn builder() -> ResultSetMetadataBuilder

Creates a new builder-style object to manufacture ResultSetMetadata.

Trait Implementations

impl Clone for ResultSetMetadata

fn clone(&self) -> ResultSetMetadata

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ResultSetMetadata

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

Formats the value using the given formatter.

impl PartialEq for ResultSetMetadata

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