Enum SymbolTableCache 

pub enum SymbolTableCache {
    Nothing,
    SymbolTable {
        btree_addr: u64,
        heap_addr: u64,
    },
    SoftLink {
        value_offset: u32,
    },
}

The 16-byte scratch pad of a symbol table entry, read according to the entry’s cache type (H5G_cache_t / H5G__ent_decode). Modelling it as a sum type keeps the soft-link case representable: a H5G_CACHED_SLINK entry has no object header at all, and its whole content is the offset of the link’s value string in the group’s local heap.

Variants

Nothing

H5G_NOTHING_CACHED — the scratch pad holds nothing.

SymbolTable

H5G_CACHED_STAB — the child group’s B-tree and local heap.

Fields

btree_addr: u64

heap_addr: u64

SoftLink

H5G_CACHED_SLINK — this entry is a soft link, and the scratch pad holds the offset of its value string in the group’s local heap.

Fields

value_offset: u32
