box!clj
(box! v)Returns v inside a mutable box.
Returns `v` inside a mutable box.
bset!clj
(bset! b v)Sets the value of Box to v without regard to its current value.
Returns v.
Sets the value of Box to `v` without regard to its current value. Returns `v`.
bset-vals!clj
(bset-vals! b v)Sets the value of b to v. Returns [old new], the values in the
box before and after the reset.
Sets the value of `b` to `v`. Returns `[old new]`, the values in the box before and after the reset.
bswap!clj
(bswap! b f)(bswap! b f x)(bswap! b f x y)(bswap! b f x y z)(bswap! b f x y z & args)Unsafely swaps the value of the box to be: (apply f current-value-of-box args). Stateful and messy.
Unsafely swaps the value of the box to be: (apply f current-value-of-box args). Stateful and messy.
bswap-vals!clj
(bswap-vals! b f)(bswap-vals! b f x)(bswap-vals! b f x y)(bswap-vals! b f x y z)(bswap-vals! b f x y z & args)Unsafely swaps the value of the box to be:
(apply f current-value-of-box args).
Returns [old new]
Stateful and messy.
Unsafely swaps the value of the box to be: (apply f current-value-of-box args). Returns `[old new]` Stateful and messy.
def-short-circuiting-mergecljmacro
(def-short-circuiting-merge name count-fn merge-fn)Define a short-circuiting merge function. Will use the provided
count-fn and merge-fn.
Example:
(def-short-circuiting-merge sc-merge count merge)
Can take advantage of inline implementations as well.
Define a short-circuiting merge function. Will use the provided `count-fn` and `merge-fn`. Example: (def-short-circuiting-merge sc-merge count merge) Can take advantage of `inline` implementations as well.
entry-atclj
(entry-at m k)Returns the map-entry mapped to key or nil if key not present.
Returns the map-entry mapped to key or nil if key not present.
fast-assocclj
(fast-assoc a k v)Like assoc but only takes one kv pair. Slightly faster.
Like assoc but only takes one kv pair. Slightly faster.
fast-countclj
(fast-count coll)like [[clojure.core/count]] but works only for clojure.lang.Counted collections.
like [[clojure.core/count]] but works only for clojure.lang.Counted collections.
fast-map-mergeclj
(fast-map-merge x y)Returns a map that consists of the second of the maps assoc-ed onto the first. If a key occurs in more than one map, the mapping from te latter (left-to-right) will be the mapping in the result.
Returns a map that consists of the second of the maps assoc-ed onto the first. If a key occurs in more than one map, the mapping from te latter (left-to-right) will be the mapping in the result.
fast-update-inclj
(fast-update-in m ks f)(fast-update-in m ks f a)(fast-update-in m ks f a b)(fast-update-in m ks f a b c)(fast-update-in m ks f a b c & args)rmerge!clj
(rmerge! l r)Returns a transient map that consists of the second of the maps assoc-ed onto the first. If a key occurs in more than one map, the mapping from te latter (left-to-right) will be the mapping in the result.
Returns a transient map that consists of the second of the maps assoc-ed onto the first. If a key occurs in more than one map, the mapping from te latter (left-to-right) will be the mapping in the result.
short-circuiting-mergeclj
(short-circuiting-merge count-fn merge-fn)Return a function which will merge two maps and short circuit if any of them are empty or nil.
Return a function which will merge two maps and short circuit if any of them are empty or nil.
val-atclj
(val-at m k)(val-at m k nf)Returns the value mapped to key or nil if key not present.
Returns the value mapped to key or nil if key not present.
