pub struct CollationMetadataV1 {
pub bits: u32,
}
Expand description
Each non-alias collation that the data provider knows about explicitly has an data entry at least for this struct.
Fields
bits: u32
See the mask constants in the impl
block for the
bit layout. The other bits are ignored: They could
be from the future if their semantics such that
old code may ignore them.
Note: At present, it’s bogus for the bit for “upper first” to be set if “case first” isn’t also set. However, the methods handle this case gracefully, so there is no need for invariant validation.
