Timecode, a standard type

An address of one frame in a video: hours, minutes, seconds and frames.

Use it for video editing. It holds its frame rate, so a time on its own isn't enough. For a plain amount of time, use Duration.

Shape

Field	Type	Required?
`hours`	`Int`	Yes
`minutes`	`Int`	Yes
`seconds`	`Int`	Yes
`frames`	`Int`	Yes
`rate`	`FrameRate`	Yes
`drop_frame`	`Bool`	Yes

Its parts keep these rules, and a value that breaks one fails with the rule's name:

frames_within_rate: frames is below the rate's whole frames a second
drop_frame_rate: drop_frame only at 30000/1001 or 60000/1001
frame_not_dropped: a drop-frame timecode is never a label drop-frame counting skips

Example

example

Timecode {    hours: 1    minutes: 0    seconds: 0    frames: 0    rate: FrameRate { numerator: 25 denominator: 1 }    drop_frame: false}

Good to know

drop_frame works only at 30000/1001 or 60000/1001.
It has no single text form, so text.parse won't take it.
== tells you whether two are the same. < and list.sort_by don't take it, so sort by one of its parts instead.

In JSON

An object of its parts, in a request, a response or json.write:

json

{"hours":1,"minutes":0,"seconds":0,"frames":0,"rate":"25/1","drop_frame":false}{"hours":0,"minutes":10,"seconds":0,"frames":0,"rate":"30000/1001","drop_frame":true}{"hours":0,"minutes":1,"seconds":0,"frames":2,"rate":"30000/1001","drop_frame":true}

Details

Text form, storage, how it is shown, and operations

Timecode is in the group Media and visual, and has been in Jadpo since 0.1.0.

Text form

It has no single text form, so text.from and text.parse don't take it.

How it is stored

It is stored in 7 columns, each named for the field, _ and its suffix. This is {"hours":0,"minutes":1,"seconds":0,"frames":2,"rate":"30000/1001","drop_frame":true}:

Column	Type	Holds
`<field>_hours`	`smallint`	`0`
`<field>_minutes`	`smallint`	`1`
`<field>_seconds`	`smallint`	`0`
`<field>_frames`	`smallint`	`2`
`<field>_rate_numerator`	`integer`	`30000`
`<field>_rate_denominator`	`integer`	`1001`
`<field>_drop_frame`	`boolean`	`TRUE`

How it is shown to people

text.format(value, locale:) shows it to people in their locale.

With locale: Locale.en_gb:

Value	Shown
`{"hours":1,"minutes":0,"seconds":0,"frames":0,"rate":"25/1","drop_frame":false}`	`01:00:00:00`
`{"hours":0,"minutes":10,"seconds":0,"frames":0,"rate":"30000/1001","drop_frame":true}`	`00:10:00;00`
`{"hours":0,"minutes":1,"seconds":0,"frames":2,"rate":"30000/1001","drop_frame":true}`	`00:01:00;02`
`{"hours":23,"minutes":59,"seconds":59,"frames":59,"rate":"60000/1001","drop_frame":false}`	`23:59:59:59`

Operations

It also takes text.format, json.read, json.write and ==. How every standard type behaves says how they work.
