Struct RefreshPolicy 

pub struct RefreshPolicy {
    pub policy_type: Option<String>,
    pub source_expression: Option<String>,
    pub change_detection: Option<String>,
}

A table’s incremental refresh policy (TMDL refreshPolicy / TOM refreshPolicy).

Only the expressions are modeled. The policy’s ranges, periods, and offsets cannot consume a model object, so they are skipped as Tier-1 metadata — but both expression properties are evaluated at refresh time, where deleting what they reference breaks refresh (see crate::m and DaxExpressionKind::ChangeDetection).

Fields

policy_type: Option<String>

Policy type as written (TOM policyType, e.g. basicRefreshPolicy). Diagnostics only.

source_expression: Option<String>

The policy’s source expression (TOM sourceExpression): the M query new policy-range partitions are created from, filtered by the RangeStart/RangeEnd parameters.

change_detection: Option<String>

The change-detection expression (TOM pollingExpression): evaluated per partition at refresh time to decide whether the partition has new data.
