Struct Snapshot 

pub struct Snapshot<S: SnapshotState = Unsorted> { /* private fields */ }

Implementations

impl Snapshot<Unsorted>

pub fn from_extracted( header: SnapshotHeader, modules: Vec<Module>, headers: Vec<HrlFile>, ) -> Self

pub fn with_apps(self, apps: Vec<AppManifest>) -> Self

pub fn with_cuttlefish( self, schemas: Vec<SchemaFile>, partials: Vec<PartialFile>, ) -> Self

pub fn into_canonical(self) -> Snapshot<Canonical>

impl<S: SnapshotState> Snapshot<S>

pub fn header(&self) -> &SnapshotHeader

pub fn modules(&self) -> &[Module]

pub fn headers(&self) -> &[HrlFile]

pub fn apps(&self) -> &[AppManifest]

pub fn schemas(&self) -> &[SchemaFile]

pub fn partials(&self) -> &[PartialFile]

pub fn records(&self) -> impl Iterator<Item = &RecordDecl>

Records are declared in headers (.hrl) and inline in modules (.erl): both.

impl Snapshot<Canonical>

pub fn lookup_export( &self, module: &ModuleName, function: &FunctionName, arity: Arity, ) -> bool

True when module exports function/arity. O(log n): canonical snapshots keep modules and each module’s exports sorted.

pub fn module_named(&self, name: &ModuleName) -> Option<&Module>

Look up a module by name in O(log n): canonical snapshots keep modules sorted by name.

pub fn implementers_of(&self, behaviour: &ModuleName) -> Vec<&Module>

Every module whose -behaviour(B). list contains behaviour. Reverse index over Module.behaviours; built per call (one linear scan over self.modules). Used by behaviour-conformance checks and the R7 suite-implementer sweep.

pub fn written_format_version(&self) -> u32

pub fn unwritable_reason(&self) -> Option<String>
