Struct RuntimeToken 

pub struct RuntimeToken(/* private fields */);

The default runtime-checked token type.

Because this token type is checked at runtime, it can make sense to have a global token type for your whole application.

And because this runtime token is backed by a u64, it would take you 60 years continuously instantiating them at 10GHz (which is unfeasible with existing hardware) before an overflow may cause multiple tokens to share the same runtime identifier; so you can safely assume that this token type will never let you access a cell that you shouldn’t be accessing.

Trait Implementations

impl Debug for RuntimeToken

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

Formats the value using the given formatter.

impl TokenTrait for RuntimeToken

type ComparisonMaySpuriouslyEq = False

Whether or not comparison between two distinct token could yield eq.

type RunError = Infallible

TokenTrait::with_token may fail, typically if construction failed.

type Identifier = u64

Lets a TokenCell keep track of the token.

type ComparisonError = IdMismatch<u64>

core::convert::Infallible unless TokenTrait::compare is fallible (ie. comparison is done at runtime).

type Branded<'a> = RuntimeToken

Rebrands the token, this is necessary for GhostToken to function properly

fn with_token<R, F: for<'a> FnOnce(Self::Branded<'a>) -> R>( f: F, ) -> Result<R, Self::RunError>

Constructs a new, lifetime-branded Token, and provides it to the closure.

fn identifier(&self) -> Self::Identifier

Returns the Token’s identifier, which cells may store to allow comparison.

fn compare(&self, id: &Self::Identifier) -> Result<(), Self::ComparisonError>

Allows the cell to compare its identifier to the Token.

impl UnscopedToken for RuntimeToken

type ConstructionError = Infallible

Constructing a token may fail.

fn try_new() -> Result<Self, Self::ConstructionError>

Constructs a new Token.

fn new() -> Self

where Self: UnscopedToken<ConstructionError = Infallible>,

Constructs a new Token. This method may be used instead of UnscopedToken::try_new when .
