Struct ContactCardComparator 

#[non_exhaustive]
pub struct ContactCardComparator {
    pub property: ContactCardComparatorProperty,
    pub is_ascending: bool,
    pub collation: Option<String>,
}

Comparator for ContactCard/query sort order (RFC 9610 §3.3.2).

Build one with ContactCardComparator::new; the struct is #[non_exhaustive].

Excluded from extras preservation

This type is out of scope for the workspace extras-preservation policy: it carries no flatten-extras extra field, and its property field is consumed by backend dispatch to determine sort order. See ContactCardFilterCondition for the rationale and for the two recommended paths (draft-ietf-jmap-metadata, bd JMAP-ua37; or the pre-IETF sloppy-value escape).

Cross-reference: bd JMAP-lbdy “Decision: filter algebra excluded”.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

property: ContactCardComparatorProperty

The property to sort by.

is_ascending: bool

Sort direction; true = ascending (wire-default per RFC 8620 §5.5), false = descending.

collation: Option<String>

Optional collation identifier (RFC 4790).

Implementations

impl ContactCardComparator

pub fn new(property: ContactCardComparatorProperty) -> Self
