If in Linux you may need install this:

apt install -y build-essential libssl-dev pkg-config

check your PATH $HOME/.cargo/bin/slick:w

Then add this to your .zshrc:

zle -N zle-keymap-select
zle -N zle-line-init
zmodload zsh/datetime
autoload -Uz add-zsh-hook
add-zsh-hook precmd slick_prompt_precmd
add-zsh-hook preexec slick_prompt_preexec

typeset -g slick_prompt_data
typeset -g slick_prompt_timestamp

SLICK_PATH=$HOME/.cargo/bin/slick

function slick_prompt_refresh {
    local exit_status=$?
    read -r -u $1 slick_prompt_data
    PROMPT=$($SLICK_PATH prompt -k "$KEYMAP" -r $exit_status -d ${slick_prompt_data:-""} -t ${slick_prompt_timestamp:-$EPOCHSECONDS})
    unset slick_prompt_timestamp

    zle reset-prompt

    # Remove the handler and close the fd
    zle -F $1
    exec {1}<&-
}

function zle-line-init zle-keymap-select {
    PROMPT=$($SLICK_PATH prompt -k "$KEYMAP" -d ${slick_prompt_data:-""})
    zle && zle reset-prompt
}

function slick_prompt_precmd() {
    slick_prompt_data=""
    local fd
    exec {fd}< <($SLICK_PATH precmd)
    zle -F $fd slick_prompt_refresh
}

function slick_prompt_preexec() {
    slick_prompt_timestamp=$EPOCHSECONDS

    # Set cursor style
    # 0  ⇒  blinking block.
    # 1  ⇒  blinking block (default).
    # 2  ⇒  steady block.
    # 3  ⇒  blinking underline.
    # 4  ⇒  steady underline.
