Struct FileId 

pub struct FileId(pub u32);

A file identifier used to track which source file a span belongs to.

File IDs are indices into a file table maintained by the compiler. FileId(0) is reserved as the default/unknown file.

Tuple Fields

0: u32

Implementations

impl FileId

pub const DEFAULT: FileId

The default file ID, used for single-file compilation or when the file is unknown.

pub const fn new(id: u32) -> FileId

Create a new file ID from an index.

pub const fn index(self) -> u32

Get the raw index value.

Trait Implementations

impl Clone for FileId

fn clone(&self) -> FileId

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FileId

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

Formats the value using the given formatter.

impl Default for FileId

fn default() -> FileId

Returns the “default value” for a type.

impl Hash for FileId

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for FileId

fn eq(&self, other: &FileId) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
