Function datafusion::sql::parse_data_type

pub fn parse_data_type(val: &str) -> Result<DataType, DataFusionError>

Parses str into a DataType.

parse_data_type is the the reverse of DataType’s Display impl, and maintains the invariant that parse_data_type(data_type.to_string()) == data_type

Example:

let display_value = "Int32";

// "Int32" is the Display value of `DataType`
assert_eq!(display_value, &format!("{}", DataType::Int32));

// parse_data_type coverts "Int32" back to `DataType`:
let data_type = parse_data_type(display_value).unwrap();
assert_eq!(data_type, DataType::Int32);
