Struct mozpdb::SymbolIter

pub struct SymbolIter<'t> { /* fields omitted */ }

A SymbolIter iterates over a SymbolTable, producing Symbols.

Symbol tables are represented internally as a series of records, each of which have a length, a type, and a type-specific field layout. Iteration performance is therefore similar to a linked list.
