Struct DryRunReport 

pub struct DryRunReport {
    pub source_row_count: i64,
    pub mapping: Box<MappingReport>,
    pub sample_rows: Vec<HashMap<String, Value>>,
    pub source_capabilities: Box<Capabilities>,
    pub target_capabilities: Box<Capabilities>,
}

DryRunReport : Read-only preview of a migration. Alongside the mapping validation it carries both connectors’ declared Capabilities verbatim, so a caller can render what a connector cannot do – "this target is read-only", "this run is not resumable" – rather than inferring it from which warnings happen to appear in mapping. A dry run holds the target through a read-only handle precisely so it cannot write, so target_capabilities.writable is the only way it can report a read-only target.

Fields

source_row_count: i64

Row count of the source table (may be a planner estimate depending on the connector).

mapping: Box<MappingReport>

sample_rows: Vec<HashMap<String, Value>>

Up to 5 source rows, remapped to target column names, showing exactly what a real run would insert. Empty if the mapping has errors (nothing would be inserted).

source_capabilities: Box<Capabilities>

target_capabilities: Box<Capabilities>
