Struct DataModel 

pub struct DataModel {
    pub schema_format: String,
    pub type_attribute: String,
    pub entities: Vec<EntityDefinition>,
}

Application-level data model parsed from a schema file (e.g., OneTable). Designed for agent consumption — serializes to JSON for MCP responses.

Fields

schema_format: String

Schema format identifier, e.g. “onetable:1.1.0”

type_attribute: String

The attribute name used to discriminate entity types (e.g. “_type”)

entities: Vec<EntityDefinition>

Entity definitions with key templates and GSI mappings

Implementations

impl DataModel

pub fn instructions_summary(&self, limit: usize) -> Option<String>

Generate a compact summary for MCP instructions.

Returns entity names with their GSI participation, truncated to limit. If limit is 0, returns None (summary suppressed).

fn clone(&self) -> DataModel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DataModel

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

Formats the value using the given formatter.

impl Serialize for DataModel

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,
