Struct clang::TranslationUnit

pub struct TranslationUnit<'i> { /* fields omitted */ }

A preprocessed and parsed source file.

Implementations

impl<'i> TranslationUnit<'i>

pub fn from_ast<F: AsRef<Path>>(
    index: &'i Index<'_>,
    file: F
) -> Result<TranslationUnit<'i>, ()>

Constructs a new TranslationUnit from an AST file.

Failures

• an unknown error occurs

pub fn get_diagnostics(&'i self) -> Vec<Diagnostic<'i>>

Returns the diagnostics for this translation unit.

pub fn get_entity(&'i self) -> Entity<'i>

Returns the entity for this translation unit.

pub fn get_file<F: AsRef<Path>>(&'i self, file: F) -> Option<File<'i>>

Returns the file at the supplied path in this translation unit, if any.

pub fn get_memory_usage(&self) -> HashMap<MemoryUsage, usize>

Returns the memory usage of this translation unit.

pub fn get_skipped_ranges(&'i self) -> Vec<SourceRange<'i>>

Returns the source ranges in this translation unit that were skipped by the preprocessor.

This will always return an empty Vec if the translation unit was not constructed with a detailed preprocessing record.

pub fn get_target(&self) -> Target

Returns information about the target for this translation unit.

pub fn annotate(&'i self, tokens: &[Token<'i>]) -> Vec<Option<Entity<'i>>>

Returns the AST entities which correspond to the supplied tokens, if any.

pub fn completer<F: Into<PathBuf>>(
    &self,
    file: F,
    line: u32,
    column: u32
) -> Completer<'_>

Returns a completer which runs code completion.

pub fn save<F: AsRef<Path>>(&self, file: F) -> Result<(), SaveError>

Saves this translation unit to an AST file.

Failures

• errors in the translation unit prevent saving
• an unknown error occurs

pub fn reparse(
    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

Trait Implementations

impl<'i> Debug for TranslationUnit<'i>

pub fn fmt(&self, formatter: &mut Formatter<'_>) -> Result

impl<'i> Drop for TranslationUnit<'i>

pub fn drop(&mut self)

Executes the destructor for this type.
