Remove

Deletes a key from the map.

Module: Std::HashMap

Signature

func Remove(self, key: int) -> bool;

Parameters

Name	Type	Description
key	int	The key to remove.

Returns

bool — true if the key was present and removed, false if it was not found.

Description

Removes the entry for key and repairs the probe sequence so later lookups stay correct. The value pointer is simply dropped from the map — any memory it referenced is the caller's to free.

Example

import Std::HashMap::*;

if map.Remove(42) {
    // entry existed and is now gone
}
