WebFeb 27, 2024 · Writing a Binary Search Tree in Rust. Introduction. Binary Search Trees are a convenient structure for storing data because search, access, insertion, and deletion operations have an average time complexity of O (log (n)) with a worst case of O (n). It‘s also useful for sorting because insertion into a BST is inherently sorted! Web2.1 B-tree indexes B-tree indexes are, of course, well known [BC 72, C 79], so we review only a few relevant topics. Following common practice, we assume here that traditional B-tree implementations are actually B+-trees, i.e., they keep all records in the leaf nodes and they chain nodes at the leaf
