}

The program options for the code generation

Fields

debug: bool

Activate debug mode

ugly: bool

Skip running output through rustfmt

dir: bool

Program will treat output as a directory name rather than a file and generate a whole crate. If output is not provided code is printed as usual

rust_case: bool

Convert names from the database to rust standard (i.e. table names in CamelCase, fields and functions in snake_case)

rustfmt_config: Option<String>

string passed to rustfmt –config

rustfmt_config_path: Option<String>

string passed to rustfmt –config-path

no_functions: bool

Only make mappings for tables and views

use_tuples: Tuples

How to use tuples (used by default for just overloads). Options: overloads (the default, use tuples to represent function overloading). all (Have all functions take a tuple for consitency). none (skip mapping overloaded procs at all). one_overload (avoid tuples by only mapping the oldest sql proc in the database).

third_party: Vec<ThirdParty>

A comma seperated list of third party crates which contain types that will be mapped to and from sql types. Valid values are “bit_vec,chrono,eui48,geo_types,rust_decimal,serde_json,time,uuid”

conn: String

String to connect to database, see tokio_postgres::Config for details. If not provided environment variable DATABASE_URL is checked instead

output: Option<PathBuf>

Output file, stdout if not present

Implementations

impl Opt

pub fn get_cargo_toml(&self) -> String

Produce the Cargo.toml file contents (the dependecies of the generated code)

pub fn get_call_string(&self) -> String

Build a call string that could be used to get the same options

pub fn get_client(&self) -> MyClient

Trait Implementations

impl Debug for Opt

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

Formats the value using the given formatter.

impl StructOpt for Opt

fn clap<'a, 'b>() -> App<'a, 'b>

Returns clap::App corresponding to the struct.

fn from_clap(matches: &ArgMatches<'_>) -> Self

Builds the struct from clap::ArgMatches. It’s guaranteed to succeed if matches originates from an App generated by StructOpt::clap called on the same type, otherwise it must panic.

fn from_args() -> Self

where Self: Sized,

Builds the struct from the command line arguments (std::env::args_os). Calls clap::Error::exit on failure, printing the error message and aborting the program.

fn from_args_safe() -> Result<Self, Error>

where Self: Sized,

Builds the struct from the command line arguments (std::env::args_os). Unlike StructOpt::from_args, returns clap::Error on failure instead of aborting the program, so calling .exit is up to you.

fn from_iter<I>(iter: I) -> Self

where Self: Sized, I: IntoIterator, <I as IntoIterator>::Item: Into<OsString> + Clone,

Gets the struct from any iterator such as a Vec of your making. Print the error message and quit the program in case of failure.

fn from_iter_safe<I>(iter: I) -> Result<Self, Error>

where Self: Sized, I: IntoIterator, <I as IntoIterator>::Item: Into<OsString> + Clone,

Gets the struct from any iterator such as a Vec of your making.
