Enum InlinePolicy 

#[non_exhaustive]
pub enum InlinePolicy {
    Never,
    LeafIfFits(usize),
}

When maps and sequences are written on a single line in indented output.

Maps and sequences with the Layout::Compact hint are always written on a single line, the ones with Layout::Expanded never (unless they are in a map or sequence on a single line). See SerializerConfig::set_inline.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Never

Only compact maps and sequences are written on a single line.

LeafIfFits(usize)

Maps and sequences which only contain scalars (no maps or sequences, not even empty ones) are written on a single line if that line is not longer than the given number of characters (including the indentation, a tab counts as one character).
