Param

Struct Param 

Source
pub struct Param(/* private fields */);
Expand description

A bitmask of grammar parameters threaded between parse functions. Port of JSParserImpl::Param.

Implementations§

Source§

impl Param

Source

pub fn plus(self, b: Param) -> Param

Union (C++ operator+).

Source

pub fn minus(self, b: Param) -> Param

Difference (C++ operator-).

Source

pub fn has(self, p: Param) -> bool

True if any flag in p is set (C++ has).

Source

pub fn has_all(self, p: Param) -> bool

True if ALL flags in p are set (C++ hasAll).

Source

pub fn get(self, p: Param) -> Param

p if any of its bits are set here, else empty (C++ get). (The C++ variadic get(p, tail...) is just a.get(x).plus(a.get(y)) in Rust — single-arg get + plus cover it.)
