Struct Row

pub struct Row { /* private fields */ }

Row in a result set of a select statement

Implementations

impl Row

pub fn get<I, T>(&self, colidx: I) -> Result<T>

where I: ColumnIndex, T: FromSql,

Gets the column value at the specified index.

pub fn sql_values(&self) -> &[SqlValue<'_>]

Returns column values as a vector of SqlValue

pub fn get_as<T>(&self) -> Result<T>

where T: RowValue,

Gets column values as specified type.

Type inference for the return type doesn’t work. You need to specify it explicitly such as row.get_as::<(i32, String)>(). See RowValue for available return types.

let conn = Connection::connect("scott", "tiger", "")?;
let mut stmt = conn.statement("select empno, ename from emp").build()?;

for result in stmt.query(&[])? {
    let row = result?;
    // Gets a row as `(i32, String)`.
    let (empno, ename) = row.get_as::<(i32, String)>()?;
    println!("{},{}", empno, ename);
}

pub fn column_info(&self) -> &[ColumnInfo]
