Struct TokenMap 

pub struct TokenMap<'a, T: ?Sized, U, F: FnOnce(TokenGuard<'a, T, Token>) -> U, Cell: TokenCellTrait<T, Token> + ?Sized, Token: TokenTrait + 'a> { /* private fields */ }

An operation waiting to be applied onto a cell by providing a proof of immutable access.

Implementations

impl<'a, T: ?Sized, U, F: FnOnce(TokenGuard<'a, T, Token>) -> U, Token: TokenTrait, Cell: TokenCellTrait<T, Token>> TokenMap<'a, T, U, F, Cell, Token>

pub fn try_apply( self, token: &'a Token, ) -> Result<U, (Self, Token::ComparisonError)>

Attempt to apply the operation.

Errors

If the token comparison failed. Reaching this error is likely to be a fundamental error in your program.

pub fn apply(self, token: &'a Token) -> U

where Token: TokenTrait<ComparisonError = Infallible>,

Applies the operation.
