Struct ResultRowRef

pub struct ResultRowRef<'a> { /* private fields */ }

A reference to a Row in a ResultSet. The columns can be accessed either through their position or using the column name.

let names = vec!["id".to_string(), "name".to_string()];
let rows = vec![vec!["1234".into(), "Musti".into()]];

let result_set = ResultSet::new(names, rows);
let row = result_set.first().unwrap();

assert_eq!(row[0], row["id"]);
assert_eq!(row[1], row["name"]);

Implementations

impl<'a> ResultRowRef<'a>

pub fn at(&self, i: usize) -> Option<&ParameterizedValue<'static>>

Take a value from a certain position in the row, if having a value in that position.

assert_eq!(Some(&row[0]), row.at(0));

pub fn get(&self, name: &str) -> Option<&ParameterizedValue<'static>>

Take a value with the given column name from the row.

assert_eq!(Some(&row["id"]), row.get("id"));
