Struct parity_scale_codec::CompactRef

pub struct CompactRef<'a, T>(pub &'a T);

Compact-encoded variant of &’a T. This is more space-efficient but less compute-efficient.

Converts to this type from the input type.

impl<'a, T: PartialEq> PartialEq for CompactRef<'a, T>

fn eq(&self, other: &CompactRef<'a, T>) -> 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.
