[−][src]Struct wirefilter::ExecutionContext
An execution context stores an associated Scheme and a
set of runtime values to execute Filter against.
It acts as a map in terms of public API, but provides a constant-time index-based access to values for a filter during execution.
Methods
impl<'e> ExecutionContext<'e>[src]
pub fn new<'s: 'e>(scheme: &'s Scheme) -> Self[src]
Creates an execution context associated with a given scheme.
This scheme will be used for resolving any field names and indices.
pub fn scheme(&self) -> &'e Scheme[src]
Returns an associated scheme.
pub fn set_field_value<'v: 'e, V: Into<LhsValue<'v>>>(
&mut self,
name: &str,
value: V
) -> Result<(), FieldValueTypeMismatchError>[src]
&mut self,
name: &str,
value: V
) -> Result<(), FieldValueTypeMismatchError>
Sets a runtime value for a given field name.
