Module io 

Source
Expand description

Object store access for WAL objects: a deterministic key layout and conditional creates that make a retry of the same object a no-op.

Structs§

ListedObject 🔒
An object discovered by a LIST.
ObjectStoreIo 🔒
Reads and writes the WAL objects under one prefix.

Enums§

PutResult 🔒
Outcome of a conditional create.

Constants§

OBJECT_SEQ_WIDTH 🔒
Width of the zero-padded object sequence in an object key, wide enough for u64::MAX so that lexicographic and numeric order agree.
OBJECT_SUFFIX 🔒

Functions§

normalize_prefix 🔒
reports_existing_object 🔒
Returns true when a conditional create failed because the object exists. Only the precondition failure says so: a store may report AlreadyExists for an unrelated path, such as a parent that is a file.
