pub struct RuntimeToken(/* private fields */);
Expand description
A small token that’s also checked at runtime, ensuring that a TokenCell
is never accidentally used with another instance of the same token type.

unless TokenTrait::compare
is fallible (ie. comparison is done at runtime).Source§type Branded<'a> = RuntimeToken
type Branded<'a> = RuntimeToken
Rebrands the token, this is necessary for

fn with_token<R, F: FnOnce(Self) -> R>(f: F) -> Result<R, Self::RunError>
Constructs a new, lifetime-branded Token, and provides it to the closure. Read more
Source§fn identifier(&self) -> Self::Identifier
fn identifier(&self) -> Self::Identifier
Returns the Token’s identifier, which cells may store to allow comparison.
Source§fn compare(&self, id: &Self::Identifier) -> Result<(), Self::ComparisonError>
fn compare(&self, id: &Self::Identifier) -> Result<(), Self::ComparisonError>
Allows the cell to compare its identifier to the Token. Read more
