Struct QueryLog 

pub struct QueryLog<'a> { /* private fields */ }

Measures one in-flight database operation and emits the toasty::query event when finished.

Construct with sql or operation immediately before executing, then call finish with the execution result. Timing runs from construction to finish.

Implementations

impl<'a> QueryLog<'a>

pub fn sql<'v>( config: &QueryLogConfig, system: &'static str, sql: &'a str, params: impl IntoIterator<Item = &'v Value>, ) -> Self

Starts measuring a SQL statement execution.

pub fn operation( config: &QueryLogConfig, system: &'static str, operation: &'a str, collection: Option<&'a str>, ) -> Self

Starts measuring a key-value operation execution.

pub fn rows(&mut self, rows: u64)

Records the number of rows returned, for drivers that know it before handing back a stream. Row counts for count-style responses are read from the ExecResponse in finish automatically.

pub fn finish(self, result: &Result<ExecResponse>)

Emits the toasty::query event describing result.

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

Formats the value using the given formatter.
