Selection

An ordered, materialized Enumerable over one captured entity type.

Source and package

struct LibTmux.Selection struct libtmux [source] ¶: Description#

Enumeration never refreshes or performs I/O. where/2 accepts predicate data; filter/2 accepts unary Elixir functions with Enum truthiness. Holding a selection retains its snapshot graph. Enum.to_list/1 projects ordinary values when graph context is no longer needed.

count/2 function Counts observed matching items; use size/1 for cached unfiltered size.
filter/2 function Filters with a unary local function; normal predicate exceptions propagate.
one!/2 function Returns exactly one match or raises its cardinality error.
where/2 function Filters validated data while retaining order and captured graph context.
member_id?/2 function Checks native identity separately from Enumerable element membership.
one/2 function Returns exactly one match, or a structured cardinality error; stops at the second match.
one_or_nil/2 function Returns one match or nil; a second match remains an error.

exists?/2 function Returns true on the first matching observed item.
new/2 function Materializes the observed items of an entity without I/O.
one_or_nil!/2 function Returns one match or nil, raising on multiple matches.
size/1 function Returns cached materialized size in constant time.
t/0: t() :: t(LibTmux.Schema.observation()) typealias A selection without a concrete observation type; use t:t/1 to preserve item types.
t/1 typealias An ordered selection retaining items of one observation type and their originating snapshot.
