Crate rax[−][src]
Structs
| GenericError | |
| RaxIterator | |
| RaxMap |
Redis has a beautiful Radix Tree implementation in ANSI C. This brings it to Rust and creates a safe Map like wrapper for it. This is very similar in utility to a BTreeMap, but RAX is likely much faster and more efficient. Naive testing showed a 2x-4x improvement for all common operations. The only disadvantage to BTreeMap is that BTree's allow much more flexibility in regards to comparing keys. Radix trees are lexicographically only. Composite keys where the non-last member is variable length could be something BTrees could handle much easier. |
| RaxSet |
RaxMap but without the values. The "isnull" bit will be set for all entries. #Examples |
| rax | |
| raxIterator | |
| raxNode | |
| raxStack |

Traits
| RaxKey |
Same as RaxMap except values are not pointers to heap allocations.
Instead the "data pointer" in the RAX is the value. This means we
have sizeof |
Functions
| allocator⚠ |
Return the existing Rax allocator. |
| raxEOF⚠ | |
| raxShow⚠ | |
| set_allocator⚠ |
Rax internally makes calls to "malloc", "realloc" and "free" for all of it's heap memory needs. These calls can be patched with the supplied hooks. Do not call this method after Rax has been used at all. This must be called before using or calling any other Rax API function. |
