Struct LoadDataOp 

pub struct LoadDataOp {
    pub format: LoadDataFormat,
    pub with_headers: bool,
    pub path: String,
    pub variable: String,
    pub field_terminator: Option<char>,
}

LOAD DATA operator: reads a file and produces rows.

With headers (CSV), each row is bound as a Value::Map with column names as keys. Without headers (CSV), each row is bound as a Value::List of string values. JSONL always produces Value::Map. Parquet always produces Value::Map.

Fields

format: LoadDataFormat

File format.

with_headers: bool

Whether the file has a header row (CSV only, ignored for JSONL/Parquet).

path: String

File path (local filesystem).

variable: String

Variable name to bind each row to.

field_terminator: Option<char>

Field separator character (CSV only, default: comma).
