Implementations

impl Options

pub fn from_default_env() -> Result<Self, ParseOptionError>

Construct lossy rune options from the RUNEFLAGS environment variable.

pub fn available() -> &'static [OptionMeta]

Get a list and documentation for all available compiler options.

pub fn parse_option(&mut self, option: &str) -> Result<(), ParseOptionError>

Parse a compiler option. This is the function which parses the <option>[=<value>] syntax, which is used by among other things the Rune CLI with the -O <option>[=<value>] option.

It can be used to consistenly parse a collection of options by other programs as well.

pub fn test(&mut self, _enabled: bool)

Enable the test configuration flag.

pub fn debug_info(&mut self, enabled: bool)

Set if debug info is enabled or not. Defaults to true.

pub fn link_checks(&mut self, enabled: bool)

Set if link checks are enabled or not. Defaults to true. This will cause compilation to fail if an instruction references a function which does not exist.

pub fn macros(&mut self, enabled: bool)

Set if macros are enabled or not. Defaults to false.

pub fn bytecode(&mut self, enabled: bool)

Set if bytecode caching is enabled or not. Defaults to false.

pub fn memoize_instance_fn(&mut self, enabled: bool)

Memoize the instance function in a loop. Defaults to false.

pub fn script(&mut self, enabled: bool)

Whether to build sources as scripts where the source is executed like a function body.
