Enum rustc_middle::middle::exported_symbols::SymbolExportLevel [−][src]
pub enum SymbolExportLevel {
C,
Rust,
}
Expand description
The SymbolExportLevel of a symbols specifies from which kinds of crates
the symbol will be exported. C
symbols will be exported from any
kind of crate, including cdylibs which export very few things.
Rust
will only be exported if the crate produced is a Rust
dylib.

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 DepNode
s 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.
