rusty_btreec's Issues

Strings get mangled when retrieved

Using either String or CString type causes mangling of returned values. I was expecting that for String but having CString types mangled is unexpected. Need to investigate what's causing the problem

Test case:

rusty_btreec/src/lib.rs

Lines 230 to 239 in 593814b

    
           btree.set(User::new("Dale", "Murphy", 44)); 
        
           btree.set(User::new("Roger", "Craig", 68)); 
        
           btree.set(User::new("Jane", "Murphy", 47)); 
        
           assert_eq!(btree.count(), 3); 
        
           btree.ascend(None, |item| { 
        
               eprintln!("item {:#?}", item); 
        
               ascending.push(format!("{} {} {}", item.first, item.last, item.age)); 
        
               true 
        
           });

Using String:

---- ascend_descend stdout ----
a User {
    first: "Roger",
    last: "Craig",
    age: 68,
} b User {
    first: "Crai",
    last: "Rogery",
    age: 44,
} cmp Less
a User {
    first: "Jane",
    last: "Murphy",
    age: 47,
} b User {
    first: "Murph",
    last: "Janeg",
    age: 68,
} cmp Greater
a User {
    first: "Jane",
    last: "Murphy",
    age: 47,
} b User {
    first: "Jane",
    last: "Murphy",
    age: 44,
} cmp Equal

Using CString:

---- ascend_descend stdout ----
a User {
    first: "Roger",
    last: "Craig",
    age: 68,
} b User {
    first: "Crai",
    last: "Roger\x00",
    age: 44,
} cmp Less
a User {
    first: "Jane",
    last: "Murphy",
    age: 47,
} b User {
    first: "Murph",
    last: "Jane\x00",
    age: 68,
} cmp Greater
a User {
    first: "Jane",
    last: "Murphy",
    age: 47,
} b User {
    first: "Jane",
    last: "Murphy",
    age: 44,
} cmp Equal
