Struct QueryFileParams 

pub struct QueryFileParams {
    pub path: String,
    pub sql: String,
    pub table_name: Option<String>,
    pub schema: Option<Value>,
    pub json_extract_path: Option<String>,
}

Parameters for the query_file one-shot tool.

Fields

path: String

Absolute path to a CSV, Parquet, or Arrow IPC file.

sql: String

SQL query to run. Reference the table by table_name (default: filename stem).

table_name: Option<String>

Table name exposed to the SQL query (default: filename stem).

schema: Option<Value>

Partial schema override keyed by column name: {"col": "BIGINT", ...}. See the docs on QueryDataParams for the full spec. Call inspect_file first if you are unsure of the correct types.

json_extract_path: Option<String>

Optional dot-separated path to extract a nested data array from the JSON file. Numeric segments index into arrays (e.g., content.0). String values encountered during navigation are automatically parsed as JSON, handling the common pattern where MCP tool responses contain stringified JSON payloads.

Trait Implementations

Deserialize this value from the given Serde deserializer.

impl JsonSchema for QueryFileParams

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema
