Implementations

impl<'a> PredicateView<'a>

pub fn as_bytes(&self) -> &'a [u8]

pub fn target_function_id(&self) -> PluginResult<[u8; 16]>

pub fn operator_class_id(&self) -> PluginResult<[u8; 16]>

pub fn indexed_argument(&self) -> PluginResult<u16>

pub fn argument_count(&self) -> PluginResult<u16>

pub fn constant<T: ValueType>(&self, index: u16) -> PluginResult<Option<T>>

Decode one normalized constant. None is SQL NULL; the indexed-column marker is not a constant and is rejected.
