[−][src]Module smart_access::stdlib_impls
Implementation of At
for stdlib collections. Toggled with
std_collections
feature.
The following traits are implemented:
At<usize, View=T> for Vec<T>
: simple indexingAt<range, View=Vec<T>> for Vec<T>
: subvector (its size can be changed); Warning: access is O(n), wrap vector in&mut[..]
to get O(1) accessAt<K, View=V> for <Some>Map<K,V>
: access value if it is presentAt<(K,V), View=V> for <Some>Map<K,V>
: ensure that the value is present (using the provided default) then access it
Though in normal circumstances these implementations do not panic
there exists a possibility of panicking. For example
At<range> for Vec<T>
splits vector into (at most) three parts
then glues them back after the update. Every one of these actions
can panic on Out Of Memory.
