Implementations
impl Row
[src]
impl Row
[src]pub fn columns(&self) -> &[Column]ⓘ
[src]
Returns information about the columns of data in the row.
pub fn is_empty(&self) -> bool
[src]
Determines if the row contains no values.
pub fn len(&self) -> usize
[src]
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>,
[src]
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>,
[src]
I: RowIndex + Display,
T: FromSql<'a>,
Like Row::get
, but returns a Result
rather than panicking.
