pub struct SpareCapacity<'a, T>(/* private fields */);
Available on crate feature
alloc
only.Expand description
A type that implements Buffer
by appending to a Vec
, up to its
capacity.
To use this, use the spare_capacity
function.
Because this uses the capacity, and never reallocates, the Vec
should
have some non-empty spare capacity.
