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

    pub struct SourceFile { /* fields omitted */ }

🔬 This is a nightly-only experimental API. (`proc_macro` #38356)

The source file of a given `Span`.

## Methods

### `impl SourceFile`
[src]

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

🔬 This is a nightly-only experimental API. (`proc_macro` #38356)

Get the path to this source file.

### Note

If the code span associated with this `SourceFile` was generated by an external 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 `-Z 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` #38356)

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

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
