SessionStore

In-memory registry of live sessions. Single process, no persistence: this is the constraint that a multi-replica deploy would break.

Constants

CODE_ALPHABET = "ABCDEFGHJKLMNPQRSTUVWXYZ23456789"

Unambiguous alphabet: no 0/O, no 1/I, so a code read aloud is unmistakable.

CODE_LENGTH = 4

new(ttl : Time::Span = 3.hours)

find(code : String) : Session | Nil

open(now : Time = Time.utc) : Session

sweep(now : Time = Time.utc) : Int32

Removes every expired session and returns how many were dropped.
