Struct MemvidFilter 

pub struct MemvidFilter {
    pub uri: Option<String>,
    pub scope: Option<String>,
    pub as_of_frame: Option<u64>,
    pub as_of_ts: Option<i64>,
    pub cursor: Option<String>,
    pub no_sketch: Option<bool>,
    /* private fields */
}

A filter clause supported by MemvidStore.

Memvid’s query model does not support arbitrary boolean predicates; this filter only carries the restriction parameters that map onto fields of SearchRequest:

Predicate	Effect on the search request
eq("uri", "...")	request.uri = Some(value)
eq("scope", "...")	request.scope = Some(value)
eq("as_of_frame", n)	request.as_of_frame
eq("as_of_ts", n)	request.as_of_ts
eq("cursor", "...")	request.cursor (pagination)
eq("no_sketch", true/false)	disable sketch pre-filtering

gt, lt, and or are not representable; constructing such a filter produces an error at query time (MemvidError::UnsupportedFilter).

Fields

uri: Option<String>

Optional URI prefix restriction.

scope: Option<String>

Optional logical scope.

as_of_frame: Option<u64>

Optional point-in-time frame id.

as_of_ts: Option<i64>

Optional point-in-time unix-millis timestamp.

cursor: Option<String>

Optional pagination cursor (opaque token returned by a prior search).

no_sketch: Option<bool>

If Some(true), disable the sketch pre-filter for this query.

Implementations

impl MemvidFilter

pub fn is_valid(&self) -> bool

Returns true when this filter has no recorded validity problems. Filters with is_valid() == false are rejected by the search path with MemvidError::UnsupportedFilter.

Callers that build a MemvidFilter programmatically (for example through Rig’s SearchFilter combinators) can use this pair with MemvidFilter::errors to surface the failure before issuing the query.

pub fn errors(&self) -> &[String]

Human-readable reasons why this filter cannot be applied, or an empty slice when MemvidFilter::is_valid returns true.
