Module coil-stdlib

`collections::vec`

These are free functions that take the vector first: map(xs, f). The methods on Vec itself (push, pop, len, …) are in the prelude.

Part of coil-stdlib. spool projects get it automatically; with plain coil, pass --root ~/.coil/stdlib/src.

Import what you use (use path::* is not allowed):

use collections::vec::{Partitioned, fold_int};

Types#

Name	Description
`Partitioned`	Two-bucket result of `partition` (`matched` = pred true, `rest` = pred false).

Name	Description
`fold_int`	The same as `fold`; kept for older code.
`contains`	Returns `true` when `needle` is in `xs`.
`index_of`	Returns the index of the first `needle` in `xs`, or `-1`.
`binary_search`	Finds `needle` in the ascending vector `xs` by halving, and returns an index holding it.
`dedup`	Returns `xs` with runs of equal neighbours collapsed to one value.
`map`	Returns a new vector with `mapper` applied to each element, in order.
`filter`	Returns the elements for which `pred` is `true`, in order.
`first`	Returns the first element, or `None` when `xs` is empty.
`last`	Returns the last element, or `None` when `xs` is empty.
`concat`	Returns a new vector holding the elements of `a` followed by those of `b`.
`chunks`	Consecutive non-overlapping slices of `size` (last slice may be short).
`windows`	Overlapping sliding windows of exact `size`.
`partition`	Split `xs` into (`matched`, `rest`) by `pred`.
`fold`	Combines the elements left to right: starts from `init` and replaces the accumulator with `folder(acc)(x)` for each `x`.
