Struct FileId 

pub struct FileId(/* private fields */);

An opaque handle to one interned source file.

FileIds are only ever minted by SourceMap::intern; they are pure identity tokens and must never be constructed by hand. The field is private, which keeps the construction surface closed across crate boundaries.

Implementations

impl FileId

pub const SYNTHETIC: FileId

The synthetic file id used for diagnostics that are not tied to any real source location (for example a CLI usage error). It sits at the top of the id space: SourceMap::intern mints from 0 upward and panics rather than reach it.

pub const fn to_u32(self) -> u32

Trait Implementations

impl Clone for FileId

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for FileId

fn partial_cmp(&self, other: &FileId) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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