Struct ColumnUnnestList

pub struct ColumnUnnestList {
    pub output_column: Column,
    pub depth: usize,
}

Represent the unnesting operation on a list column, such as the recursion depth and the output column name after unnesting

Example: given ColumnUnnestList { output_column: "output_name", depth: 2 }

  input             output_name
 ┌─────────┐      ┌─────────┐
 │{{1,2}}  │      │ 1       │
 ├─────────┼─────►├─────────┤           
 │{{3}}    │      │ 2       │           
 ├─────────┤      ├─────────┤           
 │{{4},{5}}│      │ 3       │           
 └─────────┘      ├─────────┤           
                  │ 4       │           
                  ├─────────┤           
                  │ 5       │           
                  └─────────┘

Trait Implementations

impl Clone for ColumnUnnestList

fn clone(&self) -> ColumnUnnestList

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ColumnUnnestList

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

Formats the value using the given formatter.

impl Display for ColumnUnnestList

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

Formats the value using the given formatter.

impl Hash for ColumnUnnestList

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ColumnUnnestList

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

impl PartialOrd for ColumnUnnestList

fn partial_cmp(&self, other: &ColumnUnnestList) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
