Struct BarrelInfo 

pub struct BarrelInfo {
    pub local: Vec<CompactStr>,
    pub star: Vec<ImportRecordIdx>,
    pub named: FxHashMap<CompactStr, ExportSource>,
}

Fields

local: Vec<CompactStr>

export const a = 1

star: Vec<ImportRecordIdx>

export * from './x'

named: FxHashMap<CompactStr, ExportSource>

export { a } from './x' or export * as ns from './x'

Implementations

impl BarrelInfo

pub fn take_needed_records( &mut self, imports: &ImportedExports, imported_exports_per_record: &mut FxHashMap<ImportRecordIdx, ImportedExports>, ) -> FxHashMap<ImportRecordIdx, ImportedExports>

Determine which import records need to be loaded based on requested exports.

This method consumes entries from imported_exports_per_record and returns the records that must be loaded to satisfy imports.

Behavior

• If imports is All: returns all records (takes entire imported_exports_per_record)
• If imports is Partial with names:
  • Named exports are resolved to their source records
  • Missing names are searched in star re-exports
  • If any local (own) export is used, all non-re-export import records must be loaded (since the barrel module itself needs to execute)

Side effects

• Consumes matched entries from imported_exports_per_record
• Removes matched entries from self.named
• Clears self.local if a local export is used
