Implementations§

source§

impl<'tcx> CodegenUnitNameBuilder<'tcx>

source

pub fn new(tcx: TyCtxt<'tcx>) -> Self

source

pub fn build_cgu_name<I, C, S>( &mut self, cnum: CrateNum, components: I, special_suffix: Option<S>, ) -> Symbol
where 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).

source

pub fn build_cgu_name_no_mangle<I, C, S>( &mut self, cnum: CrateNum, components: I, special_suffix: Option<S>, ) -> Symbol
where I: IntoIterator<Item = C>, C: Display, S: Display,

Same as CodegenUnit::build_cgu_name() but will never mangle the resulting name.
