Implementations§

Source§

impl Params

Source

pub fn convert(params: &[RowValues]) -> Result<Self, SqlMiddlewareDbError>

Convert middleware row values into SQLite values.

§Errors

Returns SqlMiddlewareDbError::ConversionError if parameter conversion fails.

Source

pub fn as_values(&self) -> &[Value]

Borrow the underlying values.

Source

pub fn as_refs(&self) -> Vec<&dyn ToSql>

Build a borrowed params slice suitable for rusqlite execution.
