Struct rustc_middle::mir::coverage::CounterValueReference[][src]

pub struct CounterValueReference {
    private: u32,
}

Fields

private: u32

Implementations

Maximum value the index can take, as a u32.

Maximum value the index can take.

Creates a new index from a given usize.

Panics

Will panic if value exceeds MAX.

Creates a new index from a given u32.

Panics

Will panic if value exceeds MAX.

Creates a new index from a given u32.

Safety

The provided value must be less than or equal to the maximum value for the newtype. Providing a value outside this range is undefined due to layout restrictions.

Prefer using from_u32.

Extracts the value of this index as a usize.

Extracts the value of this index as a u32.

Extracts the value of this index as a usize.

Counters start at 1 to reserve 0 for ExpressionOperandId::ZERO.

Returns explicitly-requested zero-based version of the counter id, used during codegen. LLVM expects zero-based indexes.

Consumers may find this more convenient to use with infallible folders than try_super_fold_with, to which the provided default definition delegates. Implementors should not override this provided default definition, to ensure that the two methods are coherent (provide a definition of try_super_fold_with instead). Read more

Returns true if self has any late-bound regions that are either bound by binder or bound by some binder outside of binder. If binder is ty::INNERMOST, this indicates whether there are any late-bound regions that appear free. Read more

Returns true if this self has any regions that escape binder (and hence are not bound by it). Read more

“Free” regions in this context means that it has any region that is not (a) erased or (b) late-bound. Read more

True if there are any un-erased free regions.

Indicates whether this value definitely references only ‘global’ generic parameters that are the same regardless of what fn we are in. This is used for caching. Read more

Indicates whether this value references only ‘global’ generic parameters that are the same regardless of what fn we are in. This is used for caching. Read more

True if there are any late-bound regions

Indicates whether this value still has parameters/placeholders/inference variables which could be replaced later, in a way that would change the results of impl specialization. Read more

Gets the TypeId of self. Read more

Immutably borrows from an owned value. Read more

Mutably borrows from an owned value. Read more

This method turns the parameters of a DepNodeConstructor into an opaque Fingerprint to be used in DepNode. Not all DepNodeParams support being turned into a Fingerprint (they don’t need to if the corresponding DepNode is anonymous). Read more

This method tries to recover the query key from the given DepNode, something which is needed when forcing DepNodes during red-green evaluation. The query system will only call this method if fingerprint_style() is not FingerprintStyle::Opaque. It is always valid to return None here, in which case incremental compilation will treat the query as having changed instead of forcing it. Read more

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
