syntax; cannot be matched against without a wildcard ..
; and struct update syntax will not work.sequence_range: ChainQueryFilterRange
Limit the results to a range of elements according to their headers.
entry_type: Option<EntryType>
Filter by EntryType
entry_hashes: Option<HashSet<EntryHash>>
Filter by a list of EntryHash
.
header_type: Option<HeaderType>
Filter by HeaderType
include_entries: bool
Include the entries in the elements
Implementations
Filter on sequence range.
Filter on entry type.
Filter on entry hashes.
Filter on header type.
Include the entries in the ElementsVec that is returned.

&self,

pub fn disambiguate_forks(
&self,
headers: Vec<HeaderHashed>
) -> Vec<HeaderHashed>ⓘ
If the sequence range supports fork disambiguation, apply it to remove headers that are not in the correct branch. Numerical range bounds do NOT support fork disambiguation, and neither does unbounded, but everything hash bounded does.
pub fn filter_headers(&self, headers: Vec<HeaderHashed>) -> Vec<HeaderHashed>ⓘ
pub fn filter_headers(&self, headers: Vec<HeaderHashed>) -> Vec<HeaderHashed>ⓘ
Filter a vector of hashed headers according to the query.
