Struct concatsql::Row

pub struct Row { /* fields omitted */ }

A single result row of a query.

Implementations

impl Row

pub fn get<T: Get>(&self, key: T) -> Option<&str>

Get the value of a column of the result row.

Examples

for row in conn.rows("SELECT 1").unwrap() {
    assert_eq!(row.get(0).unwrap(),   "1");
    assert_eq!(row.get("1").unwrap(), "1");
}

pub fn get_into<T: Get, U: FromSql>(&self, key: T) -> Result<U, Error>

Transforms and gets the columns of the result row.
⚠️ If column is NULL then execute U::from_str("").

Examples

for row in conn.rows("SELECT 1").unwrap() {
    assert_eq!(row.get_into::<_, i32>(0).unwrap(),   1);
    assert_eq!(row.get_into::<_, i32>("1").unwrap(), 1);

    assert_eq!(row.get_into::<_, String>(0).unwrap(),   "1");
    assert_eq!(row.get_into::<_, String>("1").unwrap(), "1");

    let one: u8 = row.get_into(0).unwrap();
    assert_eq!(one, 1u8);
}

pub fn column_count(&self) -> usize

Return the number of columns.

pub fn is_empty(&self) -> bool

Determines if there are any values in the row.

pub fn column_names(&self) -> Vec<&str>

Get all the column names.

Trait Implementations

impl Debug for Row

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq<Row> for Row

fn eq(&self, other: &Row) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Row) -> bool

This method tests for !=.
