Implementations§

Source§

impl SqliteFunctionCtx

Source

pub fn get_arg<'q, T>(&'q self, index: usize) -> T
where T: Decode<'q, Sqlite>,

Returns the argument at the given index, or panics if the argument number is out of bounds or the argument cannot be decoded as the requested type.

Source

pub fn try_get_arg<'q, T>( &'q self, index: usize, ) -> Result<T, Box<dyn Error + Send + Sync>>
where T: Decode<'q, Sqlite>,

Returns the argument at the given index, or None if the argument number is out of bounds or the argument cannot be decoded as the requested type.

Source

pub fn set_result<'q, R>(&self, result: R)
where R: Encode<'q, Sqlite>,

Source

pub fn set_error(&self, error_str: &str)
