# [−][src]Struct proc_macro::SourceFile

    pub struct SourceFile(_);

🔬 This is a nightly-only experimental API. (`proc_macro_span` #54725)

The source file of a given `Span`.

## Methods

### `impl SourceFile`[src]

#### `pub fn path(&self) -> PathBuf`[src]

🔬 This is a nightly-only experimental API. (`proc_macro_span` #54725)

Gets the path to this source file.

### Note

If the code span associated with this `SourceFile` was generated by an external macro, this macro, this may not be an actual path on the filesystem. Use `is_real` to check.

Also note that even if `is_real` returns `true`, if `--remap-path-prefix` was passed on the command line, the path as given may not actually be valid.

#### `pub fn is_real(&self) -> bool`[src]

🔬 This is a nightly-only experimental API. (`proc_macro_span` #54725)

Returns `true` if this source file is a real source file, and not generated by an external macro's expansion.
