Struct SpgStatement 

pub struct SpgStatement<'q> { /* private fields */ }

Prepared-statement handle. Holds:

• the source SQL (for Statement::sql),
• the embedded Statement AST handle the engine cached during prepare,
• the expected output columns (populated on first execute that returns rows; empty until then),
• an empty type-name → column-ordinal map shared with SpgRow::ColumnIndex<&str>.

Implementations

impl<'q> SpgStatement<'q>

pub fn unparsed(sql: impl Into<Cow<'q, str>>) -> Self

Build a statement handle with no parsed-AST attached (e.g. for sqlx::query("...").execute(&pool) where the adapter prepares on-the-fly inside the connection).

Trait Implementations

impl<'q> Clone for SpgStatement<'q>

fn clone(&self) -> SpgStatement<'q>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl ColumnIndex<SpgStatement<'_>> for &str

fn index(&self, stmt: &SpgStatement<'_>) -> Result<usize, Error>

Returns a valid positional index into the row or statement, ColumnIndexOutOfBounds, or, ColumnNotFound.

impl ColumnIndex<SpgStatement<'_>> for usize

fn index(&self, stmt: &SpgStatement<'_>) -> Result<usize, Error>

Returns a valid positional index into the row or statement, ColumnIndexOutOfBounds, or, ColumnNotFound.

impl<'q> Debug for SpgStatement<'q>

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

Formats the value using the given formatter.

impl<'q> Statement<'q> for SpgStatement<'q>

type Database = Spg

fn to_owned(&self) -> SpgStatement<'static>

Creates an owned statement from this statement reference. This copies the original SQL text.

fn sql(&self) -> &str

Get the original SQL text used to create this statement.

fn parameters(&self) -> Option<Either<&[SpgTypeInfo], usize>>

Get the expected parameters for this statement.

fn columns(&self) -> &[SpgColumn]

Get the columns expected to be returned by executing this statement.

fn query(&self) -> Query<'_, Spg, SpgArguments<'_>>

fn query_with<'s, A>(&'s self, arguments: A) -> Query<'s, Spg, A>

where A: IntoArguments<'s, Spg>,

fn query_as<O>(&self) -> QueryAs<'_, Spg, O, SpgArguments<'_>>

where O: for<'r> FromRow<'r, SpgRow>,

fn query_as_with<'s, O, A>(&'s self, arguments: A) -> QueryAs<'s, Spg, O, A>

where O: for<'r> FromRow<'r, SpgRow>, A: IntoArguments<'s, Spg>,

fn query_scalar<O>(&self) -> QueryScalar<'_, Spg, O, SpgArguments<'_>>

where (O,): for<'r> FromRow<'r, SpgRow>,

fn query_scalar_with<'s, O, A>( &'s self, arguments: A, ) -> QueryScalar<'s, Spg, O, A>

where (O,): for<'r> FromRow<'r, SpgRow>, A: IntoArguments<'s, Spg>,

fn column<I>(&self, index: I) -> &<Self::Database as Database>::Column

where I: ColumnIndex<Self>,

Gets the column information at index.

fn try_column<I>( &self, index: I, ) -> Result<&<Self::Database as Database>::Column, Error>

where I: ColumnIndex<Self>,

Gets the column information at index or a ColumnIndexOutOfBounds error if out of bounds.
