Implementations

source

impl<O> AssertKind<O>

source

pub fn description(&self) -> &'static str

Getting a description does not require O to be printable, and does not require allocation. The caller is expected to handle BoundsCheck separately.

source

pub fn fmt_assert_args<W: Write>(&self, f: &mut W) -> Result where
O: Debug,

Format the message arguments for the assert(cond, msg..) terminator in MIR printing.

source

default fn fingerprint_style() -> FingerprintStyle

source

default fn to_fingerprint(&self, tcx: Ctxt) -> Fingerprint

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

source

default fn to_debug_str(&self, Ctxt) -> String

source

default fn recover(Ctxt, &DepNode<<Ctxt as DepContext>::DepKind>) -> Option<T>

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: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
