source§

impl PartialEq<Token> for Token

source§

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

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

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.
source§

impl ToTokens for Token

Note: Converting a Literal will result in the loss of the suffix and typically also specific information regarding what type it is, the value itself will not be lost (large u128 numbers exceeding 127 bits may lose their last bit though).
