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.

Trait Implementations

impl Deref for PgRow

type Target = Row

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl From<Row> for PgRow

fn from(row: Row) -> Self

Converts to this type from the input type.

impl RowRef for PgRow

fn get_string(&self, c: &str) -> Result<String, RowError>

Override the trait default (which is get_str + to_string) so we can decode columns whose Postgres-side type is not TEXT but whose Rust-side codegen has emitted pub field: String:

• UUID columns — emitted as String for Prisma String @db.Uuid fields. We decode via uuid::Uuid::from_sql and stringify.
• User-defined ENUM columns — also emitted as String via FromColumn’s get_string call (see codegen for enum variants). We decode via AnyText since &str: FromSql does not accept enum types.

Without this override, the row decode fails with "error deserializing column N" and the whole query bubbles up a [P6003] type conversion error.

A matching override on get_string_opt covers nullable variants.

fn is_null(&self, c: &str) -> Result<bool, RowError>

Override the trait default (which falls back to get_str_opt, and therefore fails for non-TEXT column types like INTEGER, UUID, etc.) with a type-agnostic null probe.

NullProbe: FromSql accepts every Postgres wire type and discards the payload entirely, so Option<NullProbe> deserialises to None on NULL and Some(NullProbe) on any non-null value — regardless of the column’s OID — without attempting any byte interpretation. This is exactly what the blanket impl<T: FromColumn> FromColumn for Option<T> needs to short-circuit nullable columns of any type.

Get an optional 64-bit integer column value.

fn get_f64(&self, c: &str) -> Result<f64, RowError>

Get a float column value.

fn get_f64_opt(&self, c: &str) -> Result<Option<f64>, RowError>

Get an optional float column value.

fn get_bool(&self, c: &str) -> Result<bool, RowError>

Get a boolean column value.

fn get_bool_opt(&self, c: &str) -> Result<Option<bool>, RowError>
