Implementations

impl Row

pub fn columns(&self) -> &[Column]

Returns information about the columns of data in the row.

pub fn is_empty(&self) -> bool

Determines if the row contains no values.

pub fn len(&self) -> usize

Returns the number of values in the row.

pub fn get<'a, I, T>(&'a self, idx: I) -> T where
    I: RowIndex + Display,
    T: FromSql<'a>, 

Deserializes a value from the row.

The value can be specified either by its numeric index in the row, or by its column name.

Panics

Panics if the index is out of bounds or if the value cannot be converted to the specified type.

pub fn try_get<'a, I, T>(&'a self, idx: I) -> Result<T, Error> where
    I: RowIndex + Display,
    T: FromSql<'a>, 

Like Row::get, but returns a Result rather than panicking.

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