impl Default for PMHeader

Source §

fn default() -> PMHeader

Returns the “default value” for a type. Read more

Source §

impl PartialEq for PMHeader

Source §

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

Tests for self and other values to be equal, and is used by ==.

1.0.0§

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

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