Struct FileText 

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

The VFS leaf: one file’s UTF-8 text, as a salsa input, plus its FileId (so a query holding only a FileText can recover the id for cross-file resolution) and its res:// path (so preload/extends "res://…" resolve to the declaring file — M3).

res_path is a separate salsa input field from text: salsa tracks input fields individually (per-field revisions/durabilities — verified against salsa 0.27.1 input.rs), so a query reading only res_path (the res_path_registry) backdates across a text keystroke — exactly the firewall that protects file_class_name. It is held at MEDIUM durability (set on file add, stable across edits); text stays LOW.

Implementations

impl FileText

pub fn ingredient(db: &dyn Database) -> &IngredientImpl<Self>

pub fn ingredient_mut( zalsa_mut: &mut Zalsa, ) -> (&mut IngredientImpl<Self>, &mut Runtime)

impl FileText

pub fn new<Db_>( db: &Db_, text: Arc<str>, file_id: FileId, res_path: Option<SmolStr>, ) -> Self

where Db_: ?Sized + Database,

pub fn builder( text: Arc<str>, file_id: FileId, res_path: Option<SmolStr>, ) -> <Self as HasBuilder>::Builder

pub fn text<'db, Db_>(self, db: &'db Db_) -> &'db Arc<str>

where Db_: ?Sized + Database,

The file’s full text (interned Arc<str>; the getter returns &Arc<str>).

pub fn file_id<'db, Db_>(self, db: &'db Db_) -> FileId

where Db_: ?Sized + Database,

The opaque file id this text belongs to.

pub fn res_path<'db, Db_>(self, db: &'db Db_) -> Option<SmolStr>

where Db_: ?Sized + Database,

The file’s project-relative res:// path, if the loader supplied one (None in single-file mode / tests — then preload/extends "res://…" resolve to the seam).

pub fn set_text<'db, Db_>( self, db: &'db mut Db_, ) -> impl Setter<FieldTy = Arc<str>>

where Db_: ?Sized + Database,

pub fn set_file_id<'db, Db_>( self, db: &'db mut Db_, ) -> impl Setter<FieldTy = FileId>

where Db_: ?Sized + Database,

pub fn set_res_path<'db, Db_>( self, db: &'db mut Db_, ) -> impl Setter<FieldTy = Option<SmolStr>>

where Db_: ?Sized + Database,

pub fn default_debug_fmt(this: Self, f: &mut Formatter<'_>) -> Result

where for<'__trivial_bounds> Arc<str>: Debug, for<'__trivial_bounds> FileId: Debug, for<'__trivial_bounds> Option<SmolStr>: Debug,

Default debug formatting for this struct (may be useful if you define your own Debug impl)

Trait Implementations

impl AsId for FileText

fn as_id(&self) -> Id

fn clone(&self) -> FileText

Returns a duplicate of the value.

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

type Fields = (Arc<str>, FileId, Option<SmolStr>)

A (possibly empty) tuple of the fields for this struct.

type Revisions = [Revision; 3]

Available on non-crate feature persistence only.
