Struct Metadata 

#[non_exhaustive]
pub struct Metadata {
    pub sql_statement_execution_time: Option<Duration>,
    /* private fields */
}

The additional metadata information regarding the execution of the SQL statements.

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.

sql_statement_execution_time: Option<Duration>

The time taken to execute the SQL statements.

Implementations

impl Metadata

pub fn new() -> Self

pub fn set_sql_statement_execution_time<T>(self, v: T) -> Self

where T: Into<Duration>,

Sets the value of sql_statement_execution_time.

Example

use wkt::Duration;
let x = Metadata::new().set_sql_statement_execution_time(Duration::default()/* use setters */);

pub fn set_or_clear_sql_statement_execution_time<T>(self, v: Option<T>) -> Self

where T: Into<Duration>,

Sets or clears the value of sql_statement_execution_time.

Example

use wkt::Duration;
let x = Metadata::new().set_or_clear_sql_statement_execution_time(Some(Duration::default()/* use setters */));
let x = Metadata::new().set_or_clear_sql_statement_execution_time(None::<Duration>);

Trait Implementations

impl Clone for Metadata

fn clone(&self) -> Metadata

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Metadata

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

Formats the value using the given formatter.

impl Default for Metadata

fn default() -> Metadata

Returns the “default value” for a type.

impl Message for Metadata

fn typename() -> &'static str

The typename of this message.

impl PartialEq for Metadata

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