SetClaim

ktstr::assert::claim

Struct SetClaim 

Source 
pub struct SetClaim<'a, T: Ord + Debug> { /* private fields */ }
Expand description

Per-claim builder for BTreeSet<T> values. Same kind / because modifiers as ClaimBuilder; comparator surface is set-specific.

Implementations§

Source§

impl<'a, T: Ord + Debug> SetClaim<'a, T>

Source

pub fn kind(self, kind: DetailKind) -> Self

Source

pub fn because(self, reason: &'a str) -> Self

Source

pub fn empty(self) -> &'a mut Verdict

Pass iff the set is empty.

Source

pub fn nonempty(self) -> &'a mut Verdict

Pass iff the set is non-empty.

Source

pub fn contains(self, needle: &T) -> &'a mut Verdict

Pass iff the set contains needle.

Source

pub fn len_eq(self, n: usize) -> &'a mut Verdict

Pass iff set.len() == n.

Source

pub fn len_at_most(self, n: usize) -> &'a mut Verdict

Pass iff set.len() <= n.

Source

pub fn len_at_least(self, n: usize) -> &'a mut Verdict

Pass iff set.len() >= n.

Source

pub fn subset_of(self, whitelist: &BTreeSet<T>) -> &'a mut Verdict

Pass iff every element of value is in whitelist. Fails with the offending elements listed.

Source

pub fn disjoint_from(self, forbidden: &BTreeSet<T>) -> &'a mut Verdict

Pass iff value shares no element with forbidden. Fails with the offending elements listed.
