Struct VarMap 

pub struct VarMap { /* private fields */ }

Map from Var to a particular index

Variable indexes are automatically assigned the first time VarMap::insert is called on that variable.

Indexes are guaranteed to be tightly packed, i.e. a map vars will contains values from 0..vars.len().

For efficiency, this type does not allocate heap memory for Var::X/Y/Z.

Implementations

impl VarMap

pub fn new() -> Self

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn get(&self, v: &Var) -> Option<usize>

pub fn insert(&mut self, v: Var)

Inserts a variable if not already present in the map

The index is automatically assigned.

pub fn check_tracing_arguments<T>(&self, vars: &[T]) -> Result<(), Error>

Checks whether tracing arguments are valid

pub fn check_bulk_arguments<T, V: Deref<Target = [T]>>( &self, vars: &[V], ) -> Result<(), Error>

Check whether bulk arguments are valid

Trait Implementations

impl Default for VarMap

fn default() -> VarMap

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for VarMap

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Index<&Var> for VarMap

type Output = usize

The returned type after indexing.

fn index(&self, v: &Var) -> &Self::Output

Performs the indexing (container[index]) operation.

impl Serialize for VarMap

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
