Struct TypePredicate 

pub struct TypePredicate {
    pub asserts: bool,
    pub target: TypePredicateTarget,
    pub type_id: Option<TypeId>,
    pub parameter_index: Option<usize>,
}

Type predicate information (x is T / asserts x is T).

Fields

asserts: bool

target: TypePredicateTarget

type_id: Option<TypeId>

parameter_index: Option<usize>

Trait Implementations

impl Clone for TypePredicate

fn clone(&self) -> TypePredicate

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TypePredicate

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for TypePredicate

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for TypePredicate

fn eq(&self, other: &TypePredicate) -> 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.
