Struct NonStrict

pub(crate) struct NonStrict<E, R> {
    inner: E,
    report: R,
}

A wrapper of Expression that evaluates in a non-strict way. Basically…

• When an error occurs during chunk-level evaluation, pad with NULL for each failed row.
• Report all error occurred during row-level evaluation to the EvalErrorReport.

Fields

inner: E

report: R

Implementations

impl<E, R> NonStrict<E, R>

where E: Expression, R: EvalErrorReport,

pub fn new(inner: E, report: R) -> Self

Trait Implementations

impl<E, R> Debug for NonStrict<E, R>

where E: Debug,

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

Formats the value using the given formatter.

impl<E, R> Expression for NonStrict<E, R>

where E: Expression, R: EvalErrorReport,

fn eval_row<'life0, 'life1, 'async_trait>( &'life0 self, input: &'life1 OwnedRow, ) -> Pin<Box<dyn Future<Output = Result<Datum>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Evaluate expression on a single row, report error and return NULL if failed.

fn return_type(&self) -> DataType

Get the return data type.

fn eval<'life0, 'life1, 'async_trait>( &'life0 self, input: &'life1 DataChunk, ) -> Pin<Box<dyn Future<Output = Result<ArrayRef>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Evaluate the expression in vectorized execution. Returns an array.

fn eval_v2<'life0, 'life1, 'async_trait>( &'life0 self, input: &'life1 DataChunk, ) -> Pin<Box<dyn Future<Output = Result<ValueImpl>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Evaluate the expression in vectorized execution. Returns a value that can be either an array, or a scalar if all values in the array are the same.

fn eval_const(&self) -> Result<Datum>

Evaluate if the expression is constant.

fn input_ref_index(&self) -> Option<usize>

Get the index if the expression is an InputRef.
