Description
uuid comparison rules
Product: Tarantool
Since: 2.7.1
Audience/target: Lua devs
Root document:
SME: @olegrok
Peer reviewer: @ documentarian name
Details
Currently comparison between uuid values is supported.
Example:
u1 = uuid.fromstr('aaaaaaaa-aaaa-4000-b000-000000000001')
u2 = uuid.fromstr('bbbbbbbb-bbbb-4000-b000-000000000001')
u1 > u2 -- false
u1 >= u2 -- false
u1 <= u2 -- true
u1 < u2 -- true
Also it's possible to compare uuid values with its string
representations:
u1_str = 'aaaaaaaa-aaaa-4000-b000-000000000001'
u1 = uuid.fromstr(u1_str)
u2_str = 'bbbbbbbb-bbbb-4000-b000-000000000001'
u1 == u1_str -- true
u1 == u2_str -- false
u1 >= u1_str -- true
u1 < u2_str -- true
