Struct SidebarFilter 

pub struct SidebarFilter {
    pub column: String,
    pub operator: FilterOperator,
    pub value: FilterValue,
    pub text: String,
    pub logical_op: LogicalOperator,
    pub searched: Vec<(String, DataType)>,
}

One sidebar filter statement with its value typed against the column. The one place a statement becomes a predicate, for the table and for the script alike.

Fields

column: String

operator: FilterOperator

value: FilterValue

text: String

The value as typed, which contains matches as text whatever the column.

logical_op: LogicalOperator

searched: Vec<(String, DataType)>

The columns a find kept as a filter matches in, with their types: the one named, or every column for crate::filter_modal::ANY_COLUMN.

Implementations

impl SidebarFilter

pub fn typed_in( statement: &FilterStatement, schema: &Schema, shown: &[String], ) -> Self

Self::typed against the schema, and for a find kept over every column the columns it was kept over (or, for one that names none, the columns shown). Only columns that have text to match are searched, as in a find.

pub fn unscriptable_columns(&self) -> Vec<String>

The duration columns a kept find matches as the table writes them, which the script cannot.

pub fn typed(statement: &FilterStatement, dtype: Option<&DataType>) -> Self

pub fn problem( statement: &FilterStatement, dtype: Option<&DataType>, ) -> Option<String>

Why statement cannot compare with a column of dtype, said for the user: its value does not read as the column’s type. None when it can, and for contains and the null tests, which read no value of the column’s type.
