Enum Action 

#[non_exhaustive]
pub enum Action {
    Pass,
    Drop,
    Copy {
        take: Option<u32>,
    },
    Route,
}

An action to take on matching rules.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Pass

Instructs the kernel to do nothing, and should be used to override other rules.

Drop

Drops the packet.

Copy

Copies the packet to userspace, but it is processed as normal by the kernel. The take field optionally limits the copied data to a certain number of bytes.

Fields

take: Option<u32>

Maximum bytes to copy from each packet. None copies the entire packet.

Route

Routes the packet to userspace.
