Struct Cli 

pub struct Cli {
    pub acp: bool,
    pub prompt: Option<String>,
    pub diagnostic: bool,
    pub log_dir: Option<PathBuf>,
    pub log_file: Option<String>,

}

Claude Code ACP Agent (Rust) - Use Claude Code from any ACP client

Fields

acp: bool

Run in ACP server mode (stdio communication with editor)

prompt: Option<String>

Execute prompt directly in headless mode

diagnostic: bool

Enable diagnostic mode (auto-log to temp file)

log_dir: Option<PathBuf>

Log directory (implies diagnostic mode)

log_file: Option<String>

Log file name (implies diagnostic mode)

verbose: u8

Increase logging verbosity (-v, -vv, -vvv) Note: RUST_LOG env var takes priority over this flag

quiet: bool

Quiet mode (only errors) Note: RUST_LOG env var takes priority over this flag

otel_endpoint: Option<String>

OpenTelemetry OTLP endpoint (e.g., http://localhost:4317) When otel feature is enabled, this configures the OTLP exporter. When otel feature is disabled, this argument is accepted but ignored.

otel_service_name: String

OpenTelemetry service name

Implementations

impl Cli

pub fn is_diagnostic(&self) -> bool

Check if diagnostic mode is enabled (output to file)

Returns true if --diagnostic is set, or if --log-dir or --log-file is specified.

pub fn is_otel_enabled(&self) -> bool

Check if OpenTelemetry tracing is enabled

Returns true if --otel-endpoint is specified and the otel feature is enabled.

pub fn log_level(&self) -> Level

Get the log level based on CLI arguments

• --quiet: ERROR
• default: INFO
• -v: DEBUG
• -vv or more: TRACE

pub fn log_path(&self) -> PathBuf

Get the log file path for diagnostic mode

Uses the specified log directory and file name, or defaults to:

• Directory: system temp directory
• File: claude-code-acp-rs-YYYYMMDD-HHMMSS.log

Trait Implementations

impl Args for Cli

fn group_id() -> Option<Id>

Report the ArgGroup::id for this set of arguments

fn augment_args<'b>(__clap_app: Command) -> Command

Append to Command so it can instantiate Self via FromArgMatches::from_arg_matches_mut

Append to Command so it can instantiate self via FromArgMatches::update_from_arg_matches_mut

impl Clone for Cli

fn clone(&self) -> Cli

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl CommandFactory for Cli

fn command<'b>() -> Command

Build a Command that can instantiate Self.

fn command_for_update<'b>() -> Command

Build a Command that can update self.

impl Debug for Cli

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Cli

fn default() -> Self

Returns the “default value” for a type.

impl FromArgMatches for Cli

fn from_arg_matches(__clap_arg_matches: &ArgMatches) -> Result<Self, Error>

Instantiate Self from ArgMatches, parsing the arguments as needed.

fn from_arg_matches_mut( __clap_arg_matches: &mut ArgMatches, ) -> Result<Self, Error>

Instantiate Self from ArgMatches, parsing the arguments as needed.
