Struct hdf5::file::SymbolTableInfo

pub struct SymbolTableInfo {
    pub tree_rank: u32,
    pub node_size: u32,
}

Size of parameters used to control the symbol table nodes.

Fields

tree_rank: u32

Symbol table tree rank.

tree_rank is one half the rank of a B-tree that stores a symbol table for a group. Internal nodes of the symbol table are on average 75% full. That is, the average rank of the tree is 1.5 times the value of ik. The HDF5library uses tree_rank * 2 as the maximum number of entries before splitting a B-tree node. Since only 2 bytes are used in storing the number of entries for a B-tree node in an HDF5 file, tree_rank * 2 cannot exceed 65536.

The default value for tree_rank is 16.

node_size: u32

Symbol table node size.

node_size is one half of the number of symbols that can be stored in a symbol table node. A symbol table node is the leaf of a symbol table tree which is used to store a group. When symbols are inserted randomly into a group, the group's symbol table nodes are 75% full on average. That is, they contain 1.5 times the number of symbols specified by node_size.

The default value for node_size is 4.
