You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: port_dhcp_acquire.rs
    path of file: ./repos/wasmer/lib/wasix/src/journal/effector/syscalls
    
    the code of the file until where you have to start completion: use super::*;

impl JournalEffector {
    pub fn save_port_dhcp_acquire(ctx: &mut FunctionEnvMut<'_, WasiEnv>) -> anyhow::Result<()> {
        Self::save_event(ctx, JournalEntry::PortDhcpAcquireV1)
    }

    pub fn apply_port_dhcp_acquire(ctx: &mut FunctionEnvMut<'_, WasiEnv>) -> anyhow::Resul
    
    pub fn apply_port_dhcp_acquire(ctx: &mut FunctionEnvMut<'_, WasiEnv>) -> anyhow::Result<()> {
        crate::syscalls::port_dhcp_acquire_internal(ctx)
            .map(|r| r.map_err(|err| err.to_string()))
            .unwrap_or_else(|err| Err(err.to_string()))
            .map_err(|err| {
                anyhow::format_err!(
                    "journal restore error: failed to acquire DHCP address - {}",
                    err
                )
            })?;
        Ok(())
    }
