Tables to exclude, comma-separated (ex: logs,audit_trail)

minimal: bool

Minimal mode: columns only, without PK/FK metadata

full: bool

Full mode: columns + PK/FK/NOT NULL + relationships + constraints + indexes

output: Option<String>

Output file (default: stdout)

title: Option<String>

Diagram title (default: derived from the database name)

Implementations

impl Args

pub fn parse_csv<'a>(&self, value: Option<&'a str>) -> Vec<&'a str>

Parses comma-separated values into a vector of &str.

pub fn output_mode(&self) -> OutputMode

Determines the output mode.

pub fn parse_url(&self) -> Result<ConnectionInfo, ErdifyError>

Builds ConnectionInfo from –url or DATABASE_URL.

Trait Implementations

impl Args for Args

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

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

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

impl CommandFactory for Args

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 Args

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

Formats the value using the given formatter.

impl FromArgMatches for Args

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.

fn update_from_arg_matches( &mut self, __clap_arg_matches: &ArgMatches, ) -> Result<(), Error>

Assign values from ArgMatches to self.

fn update_from_arg_matches_mut( &mut self, __clap_arg_matches: &mut ArgMatches, ) -> Result<(), Error>

Assign values from ArgMatches to self.

impl Parser for Args

fn parse() -> Self
