Struct QueryResult 

pub struct QueryResult<'a> {
    pub value: Option<Value>,
    /* private fields */
}

Result of DQE evaluation.

Fields

value: Option<Value>

Implementations

impl QueryResult<'_>

pub fn unit(&self) -> &BsUnit

Return CU in which result values are located.

pub fn value(&self) -> &Value

Return underlying typed value representation.

pub fn into_value(self) -> Value

Return underlying typed value representation.

pub fn into_identified_value(self) -> (Identity, Value)

Return underlying value and result identity (variable or argument identity).

pub fn kind(&self) -> QueryResultKind

Return result kind:

• Root kind means that value is an argument or variable
• Expression kind means that value calculated using DQE

pub fn type_graph(&self) -> &ComplexType

Return type graph using for parse a result.

pub fn identity(&self) -> &Identity

Return result identity.

pub fn scope(&self) -> &Option<Box<[Range]>>

Return variable or argument scope. Scope is a PC ranges where value is valid, None for global or virtual variables.

pub fn with_evcx<T, F: FnOnce(&EvaluationContext<'_>) -> T>(&self, cb: F) -> T

Evaluate any function with evaluation context.

pub fn modify_value<F: FnOnce(&ParseContext<'_>, Value) -> Option<Value>>( self, cb: F, ) -> Option<Self>

Modify the underlying value and return a new result extended from the current one.

Trait Implementations

impl<'a> Clone for QueryResult<'a>

fn clone(&self) -> QueryResult<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl PartialEq for QueryResult<'_>

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
