pub fn new(tcx: TyCtxt<'tcx>) -> Self
sourcepub fn build_cgu_name<I, C, S>(
&mut self,
cnum: CrateNum,
components: I,
special_suffix: Option<S>
) -> Symbolwhere
I: IntoIterator<Item = C>,
C: Display,
S: Display,
pub fn build_cgu_name<I, C, S>( &mut self, cnum: CrateNum, components: I, special_suffix: Option<S> ) -> Symbolwhere I: IntoIterator<Item = C>, C: Display, S: Display,
CGU names should fulfill the following requirements:
- They should be able to act as a file name on any kind of file system
- They should not collide with other CGU names, even for different versions of the same crate.
Consequently, we don’t use special characters except for ‘.’ and ‘-’ and we prefix each name with the crate-name and crate-disambiguator.
This function will build CGU names of the form:
<crate-name>.<crate-disambiguator>[-in-<local-crate-id>](-<component>)*[.<special-suffix>]
<local-crate-id> = <local-crate-name>.<local-crate-disambiguator>
The ‘.’ before <special-suffix>
makes sure that names with a special
suffix can never collide with a name built out of regular Rust
identifiers (e.g., module paths).
sourcepub fn build_cgu_name_no_mangle<I, C, S>(
&mut self,
cnum: CrateNum,
components: I,
special_suffix: Option<S>
) -> Symbolwhere
I: IntoIterator<Item = C>,
C: Display,
S: Display,
pub fn build_cgu_name_no_mangle<I, C, S>( &mut self, cnum: CrateNum, components: I, special_suffix: Option<S> ) -> Symbolwhere I: IntoIterator<Item = C>, C: Display, S: Display,
Same as CodegenUnit::build_cgu_name()
but will never mangle the
resulting name.
