Struct SymbolTableNode 

pub struct SymbolTableNode {
    pub entries: Vec<SymbolTableEntry>,
}

A decoded symbol table node.

Fields

entries: Vec<SymbolTableEntry>

The symbol table entries in this node.

Implementations

impl SymbolTableNode

pub fn encode( &self, node_size: usize, sizeof_addr: usize, sizeof_size: usize, ) -> FormatResult<Vec<u8>>

Encode this node into a block of exactly node_size bytes.

A SNOD is a fixed-size record — H5G_NODE_SIZE(f), which BTreeV1Config::symbol_table_node_size computes — whatever fraction of it the entries fill, because the B-tree above it allocates every leaf the same width. The unused tail is zeroed rather than left as it was: H5G__node_create calloc’s the entry array, so a node libhdf5 wrote never carries a stale entry past num_symbols.

pub fn decode( buf: &[u8], sizeof_addr: usize, sizeof_size: usize, max_entries: u16, ) -> FormatResult<Self>

Decode a symbol table node from buf.

sizeof_addr and sizeof_size come from the superblock, and max_entries is 2 * sym_leaf_k — the node’s fixed capacity (H5Gpkg.h H5G_NODE_SIZE). A node declaring more than that is corrupt, not merely unusual, so it is rejected before its entries are read.
