Struct PgRow 

pub struct PgRow(/* private fields */);

Newtype wrapper around tokio_postgres::Row that implements prax_query::row::RowRef.

The inner row is private; use PgRow::into_inner when ownership is needed (e.g., forwarding to a tokio-postgres API that consumes Row). For read-only access, the Deref<Target = Row> impl lets you call any Row method directly.

Implementations

impl PgRow

pub fn into_inner(self) -> Row

Move the wrapped tokio_postgres::Row out of this wrapper.

Methods from Deref<Target = 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.

pub fn raw_size_bytes(&self) -> usize

Returns the raw size of the row in bytes.
