Struct deltalake::datafusion::logical_expr::Filter
source · #[non_exhaustive]pub struct Filter {
pub predicate: Expr,
pub input: Arc<LogicalPlan>,
}
Expand description
Filters rows from its input that do not match an expression (essentially a WHERE clause with a predicate expression).
Semantically, <predicate>
is evaluated for each row of the input;
If the value of <predicate>
is true, the input row is passed to
the output. If the value of <predicate>
is false, the row is
discarded.
Filter should not be created directly but instead use try_new()
and that these fields are only pub to support pattern matching
Fields (Non-exhaustive)§
This struct is marked as 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.predicate: Expr
The predicate expression, which must have Boolean type.
input: Arc<LogicalPlan>
The incoming logical plan
