pub struct Options { /* private fields */ }

Options that can be passed to the parser.

Implementations

impl Options

pub fn filepath(self, filepath: &str) -> Self

Sets the filepath option.

pub const fn line(self, line: i32) -> Self

Sets the line option.

pub fn encoding(self, encoding: &str) -> Self

Sets the encoding option.

pub const fn encoding_locked(self, locked: bool) -> Self

Sets the encoding locked option.

pub const fn frozen_string_literal(self, frozen: Option<bool>) -> Self

Sets the frozen string literal option. Some(true) freezes string literals, Some(false) keeps them mutable, and None leaves the option unset.

pub fn command_line(self, command_line: Vec<CommandLineFlag>) -> Self

Sets the command line flags.

pub const fn version(self, version: Version) -> Self

Sets the version option.

pub const fn main_script(self, main_script: bool) -> Self

Sets the main script option.

pub const fn partial_script(self, partial_script: bool) -> Self

Sets the partial script option.

pub fn scope(self, scope: Scope) -> Self

Adds a scope to the options.

pub fn scopes(self, scopes: Vec<Scope>) -> Self

Sets the scopes, replacing any previously added scopes.

pub fn build(self) -> ParseOptions

Builds the C-level parse options from these options. The returned ParseOptions must outlive any ParseResult created from it.

Panics

Panics if filepath or encoding contain interior null bytes.
