I read through every file and applied a couple of rustfmt suggestions. The brace placement and alignment of items on similar lines has been made consistent, even if neither are rustfmt's default style (a file has been put in place to enforce this). Other changes are:
• Alphabetical imports and modules
• Comma placement at the end of match blocks
• Use newlines and indentation judiciously
• Spaces around associated types
• Spaces after negations (it makes it more clear imho)
• Comment formatting
• Use early-returns and Optional `?` where appropriate
Previously if a timestamp was unavailable, it defaulted to the epoch.
Prior to this it defaulted to a zero duration.
Switch to an Option<SystemTime> and move the handling of unavailable
timestamps to rendering.
Instead of returning a Duration since the epoch from file metadata,
which cannot represent times before it, return the SystemTime directly.
Move conversion closer to where it's needed, and perform it infallibly.
This commit adds many traits, all named ‘Colours’, to the code. Each one asks for a colour needed to render a cell: the number of links asks for colours for the number and the multi-link-file special case; the file size asks for number, unit, punctuation, and device ID colours, or it can do a scale with its own colours, however it wants.
This is a step towards LS_COLORS compatibility, believe it or not. If a text cell in a column doesn’t depend on Colours to render itself, then the source of the colours is open-ended.
I am glad to have not needed any test changes here.
