Struct TokenMapMut 

pub struct TokenMapMut<'a, T: ?Sized, U, F: FnOnce(TokenGuardMut<'a, T, Token>) -> U, Cell: ?Sized, Token: TokenTrait<ComparisonMaySpuriouslyEq = ComparisonMaySpuriouslyEq> + 'a, ComparisonMaySpuriouslyEq> { /* private fields */ }

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

Implementations

impl<'a, T: ?Sized, U, F: FnOnce(TokenGuardMut<'a, T, Token>) -> U, Token: TokenTrait<ComparisonMaySpuriouslyEq = False>, Cell: TokenCellTrait<T, Token>> TokenMapMut<'a, T, U, F, Cell, Token, False>

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

where Token: TokenTrait<ComparisonError = Infallible>,

Applies the operation.

impl<'a, T: ?Sized, U, F: FnOnce(TokenGuardMut<'a, T, Token>) -> U, Token: TokenTrait<ComparisonMaySpuriouslyEq = True>, Cell: UnsafeTokenCellTrait<T, Token>> TokenMapMut<'a, T, U, F, Cell, Token, True>

pub unsafe fn try_apply( self, token: &'a mut Token, ) -> Result<U, 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.

Safety

token must refer to the exact same instance of Token as that which was used to call [Self::new].

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

where Token: TokenTrait<ComparisonError = Infallible>,

Applies the operation.
