Struct clang::TranslationUnit
[−]
[src]
pub struct TranslationUnit<'i> { /* fields omitted */ }
A preprocessed and parsed source file.
Methods
impl<'i> TranslationUnit<'i>
[src]
fn from_ast<F: AsRef<Path>>(
index: &'i Index,
file: F
) -> Result<TranslationUnit<'i>, ()>
[src]
index: &'i Index,
file: F
) -> Result<TranslationUnit<'i>, ()>
fn get_diagnostics(&'i self) -> Vec<Diagnostic<'i>>
[src]
Returns the diagnostics for this translation unit.
fn get_entity(&'i self) -> Entity<'i>
[src]
Returns the entity for this translation unit.
fn get_file<F: AsRef<Path>>(&'i self, file: F) -> Option<File<'i>>
[src]
Returns the file at the supplied path in this translation unit, if any.
fn get_memory_usage(&self) -> HashMap<MemoryUsage, usize>
[src]
Returns the memory usage of this translation unit.
fn annotate(&'i self, tokens: &[Token<'i>]) -> Vec<Option<Entity<'i>>>
[src]
Returns the AST entities which correspond to the supplied tokens, if any.
fn completer<F: Into<PathBuf>>(
&self,
file: F,
line: u32,
column: u32
) -> Completer
[src]
&self,
file: F,
line: u32,
column: u32
) -> Completer
Returns a completer which runs code completion.
fn save<F: AsRef<Path>>(&self, file: F) -> Result<(), SaveError>
[src]
Saves this translation unit to an AST file.
Failures
- errors in the translation unit prevent saving
- an unknown error occurs
fn reparse(
self,
unsaved: &[Unsaved]
) -> Result<TranslationUnit<'i>, SourceError>
[src]
self,
unsaved: &[Unsaved]
) -> Result<TranslationUnit<'i>, SourceError>
Consumes this translation unit and reparses the source file it was created from with the same compiler arguments that were used originally.
Failures
- an error occurs while deserializing an AST file
libclang
crashes- an unknown error occurs
