Struct mozjs::jsapi::OwningCompileOptions

#[repr(C)]
pub struct OwningCompileOptions {
    pub _base: ReadOnlyCompileOptions,
}

Compilation options, with dynamic lifetime. An instance of this type makes a copy of / holds / roots all dynamically allocated resources (principals; elements; strings) that it refers to. Its destructor frees / drops / unroots them. This is heavier than CompileOptions, below, but unlike CompileOptions, it can outlive any given stack frame.

Note that this roots any JS values it refers to - they’re live unconditionally. Thus, instances of this type can’t be owned, directly or indirectly, by a JavaScript object: if any value that this roots ever comes to refer to the object that owns this, then the whole cycle, and anything else it entrains, will never be freed.

Trait Implementations

impl Debug for OwningCompileOptions

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

Formats the value using the given formatter.

impl PartialEq<OwningCompileOptions> for OwningCompileOptions

fn eq(&self, other: &OwningCompileOptions) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
