Struct SpgArguments 

pub struct SpgArguments<'q> {
    pub values: Vec<SpgArgumentValue<'q>>,
}

Buffer of bound arguments for one Execute call. Indexed 0..N; PG-style $1 resolves to slot 0.

Fields

values: Vec<SpgArgumentValue<'q>>

The bound values. Vec<SpgArgumentValue> so future borrowed cases stay non-breaking.

Implementations

impl<'q> SpgArguments<'q>

pub fn into_engine_values(self) -> Vec<EngineValue>

Drain the buffer into an owned Vec<EngineValue> shaped for spg_embedded::Database::execute_prepared. Called by the connection’s execute path right before the engine dispatch.

pub fn count(&self) -> usize

Convenience: number of bound args. len() is what sqlx- core uses to validate the placeholder count at Arguments::len time.

Trait Implementations

impl<'q> Arguments<'q> for SpgArguments<'q>

type Database = Spg

fn reserve(&mut self, additional: usize, _size: usize)

Reserves the capacity for at least additional more values (of size total bytes) to be added to the arguments without a reallocation.

fn add<T>(&mut self, value: T) -> Result<(), BoxDynError>

where T: 'q + Encode<'q, Self::Database> + Type<Self::Database>,

Add the value to the end of the arguments.

fn len(&self) -> usize

The number of arguments that were already added.

fn format_placeholder<W>(&self, writer: &mut W) -> Result<(), Error>

where W: Write,

impl<'q> Clone for SpgArguments<'q>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'q> Debug for SpgArguments<'q>

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

Formats the value using the given formatter.

impl<'q> Default for SpgArguments<'q>

fn default() -> SpgArguments<'q>

Returns the “default value” for a type.
