Struct containing all kind of settings for the python vm. Mostly PyConfig in CPython.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

isolated: bool

-I

dev_mode: bool

-Xdev

install_signal_handlers: bool

Not set SIGINT handler(i.e. for embedded mode)

hash_seed: Option<u32>

PYTHONHASHSEED=x None means use_hash_seed = 0 in CPython

argv: Vec<String>

sys.argv

xoptions: Vec<(String, Option<String>)>

-Xfoo[=bar]

warnoptions: Vec<String>

-Wfoo

import_site: bool

-S

bytes_warning: u64

-b

warn_default_encoding: bool

-X warn_default_encoding, PYTHONWARNDEFAULTENCODING

inspect: bool

-i

interactive: bool

-i, with no script

write_bytecode: bool

-B

verbose: u8

verbosity level (-v switch)

quiet: bool

-q

user_site_directory: bool

-s

buffered_stdio: bool

-u, PYTHONUNBUFFERED=x

utf8_mode: u8

check_hash_pycs_mode: String

–check-hash-based-pycs

safe_path: bool

-P

int_max_str_digits: i64

-X int_max_str_digits

path_list: Vec<String>

Environment PYTHONPATH (and RUSTPYTHONPATH)

debug: bool

-d command line switch

optimize: u8

-O optimization switch counter

ignore_environment: bool

-E

allow_external_library: bool

false for wasm. Not a command-line option

Implementations

impl Settings

pub fn with_path(self, path: String) -> Self

Trait Implementations

impl Default for Settings

Sensible default settings.

fn default() -> Self

Returns the “default value” for a type.
