Implementations§

source§

impl ParseSess

source

pub(crate) fn new(config: &Config) -> Result<ParseSess, ErrorKind>

source

pub(crate) fn default_submod_path( &self, id: Ident, relative: Option<Ident>, dir_path: &Path ) -> Result<ModulePathSuccess, ModError<'_>>

Determine the submodule path for the given module identifier.

  • id - The name of the module
  • relative - If Some(symbol), the symbol name is a directory relative to the dir_path. If relative is Some, resolve the submodle at {dir_path}/{symbol}/{id}.rs or {dir_path}/{symbol}/{id}/mod.rs. if None, resolve the module at {dir_path}/{id}.rs.
  • dir_path - Module resolution will occur relative to this directory.
