Struct PruningStats 

#[non_exhaustive]
pub struct PruningStats {
    pub post_cmeta_pruning_partition_count: Option<i64>,
    pub pre_cmeta_pruning_parallel_input_count: Option<i64>,
    pub post_cmeta_pruning_parallel_input_count: Option<i64>,
    /* private fields */
}

The column metadata index pruning statistics.

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.

post_cmeta_pruning_partition_count: Option<i64>

The number of partitions matched.

pre_cmeta_pruning_parallel_input_count: Option<i64>

The number of parallel inputs scanned.

post_cmeta_pruning_parallel_input_count: Option<i64>

The number of parallel inputs matched.

Implementations

impl PruningStats

pub fn new() -> Self

Creates a new default instance.

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

where T: Into<i64>,

Sets the value of post_cmeta_pruning_partition_count.

Example

let x = PruningStats::new().set_post_cmeta_pruning_partition_count(42);

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

where T: Into<i64>,

Sets or clears the value of post_cmeta_pruning_partition_count.

Example

let x = PruningStats::new().set_or_clear_post_cmeta_pruning_partition_count(Some(42));
let x = PruningStats::new().set_or_clear_post_cmeta_pruning_partition_count(None::<i32>);

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

where T: Into<i64>,

Sets the value of pre_cmeta_pruning_parallel_input_count.

Example

let x = PruningStats::new().set_pre_cmeta_pruning_parallel_input_count(42);

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

where T: Into<i64>,

Sets or clears the value of pre_cmeta_pruning_parallel_input_count.

Example

let x = PruningStats::new().set_or_clear_pre_cmeta_pruning_parallel_input_count(Some(42));
let x = PruningStats::new().set_or_clear_pre_cmeta_pruning_parallel_input_count(None::<i32>);

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

where T: Into<i64>,

Sets the value of post_cmeta_pruning_parallel_input_count.

Example

let x = PruningStats::new().set_post_cmeta_pruning_parallel_input_count(42);

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

where T: Into<i64>,

Sets or clears the value of post_cmeta_pruning_parallel_input_count.

Example

let x = PruningStats::new().set_or_clear_post_cmeta_pruning_parallel_input_count(Some(42));
let x = PruningStats::new().set_or_clear_post_cmeta_pruning_parallel_input_count(None::<i32>);
