Enum JsonFilter 

pub enum JsonFilter {
    HasKey {
        column: &'static str,
        key: String,
    },
    GetText {
        column: &'static str,
        key: String,
        op: FilterOp,
        value: FilterValue,
    },
}

JSON / JSONB filter predicates. Two flavors:

• HasKey — col ? 'key' on PG (key-exists operator). On SQLite this lowers to json_extract(col, '$.key') IS NOT NULL, which has the same matches-some-non-null-value semantics for the most common case (records where the schema sometimes carries a key, sometimes doesn’t); JSON values explicitly stored as null diverge between backends, mirroring the operators themselves.
• GetText — col ->> 'key' <op> $1 on PG (extract-as-text + compare). On SQLite the same json_extract path with a column accessor handles it. Supported comparison ops are the standard Eq/Ne/Lt/Lte/Gt/Gte plus IsNull / IsNotNull.

Keys are owned String so callers can pass runtime-supplied metric / setting names (e.g. user-driven model_run_timeseries queries that pivot on args.metric). The column slot stays &'static str because columns are always schema-rooted.

Trait Implementations

impl Clone for JsonFilter

fn clone(&self) -> JsonFilter

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for JsonFilter

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

Formats the value using the given formatter.

impl PartialEq for JsonFilter

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