Struct token_cell::TokenCell

#[repr(C)]
pub struct TokenCell<Token: TokenTrait, T> { /* fields omitted */ }

A cell which requires a token for interior read/write access.

Implementations

impl<Token: TokenTrait, T> TokenCell<Token, T> where
    Token::Checker: TokenChecker<Token, Error = Infallible>, 

pub fn borrow<'l>(&'l self, _: &'l Token) -> &'l T

Borrows the cell’s content.

pub fn borrow_mut<'l>(&'l self, _: &'l mut Token) -> &'l mut T

Borrows the cell’s content mutably.

pub fn swap(&self, value: T, token: &mut Token) -> T

Places value inside the cell, returning the

impl<Token: TokenTrait, T> TokenCell<Token, T>

pub fn new(value: T) -> Self where
    Token::Checker: TokenChecker<Token, Input = ()>, 

Builds a TokenCell attached to a token

pub fn with_token(token: &Token, value: T) -> Self where
    Token::Checker: TokenChecker<Token>, 

Builds a TokenCell attached to a token

pub fn into_inner(self) -> T

pub fn try_swap(
    &self,
    value: T,
    token: &mut Token
) -> Result<T, <Token::Checker as TokenChecker<Token>>::Error>

Fallible equivalent of TokenCell::swap, for runtime-checked tokens.

Since token mismatch is indicative that the wrong token was used to interact with the cell, you should treat these as unrecoverable errors by unwrapping the result.

pub fn try_borrow<'l>(
    &'l self,
    token: &'l Token
) -> Result<&'l T, <Token::Checker as TokenChecker<Token>>::Error>

Fallible equivalent of TokenCell::borrow, for runtime-checked tokens.

Since token mismatch is indicative that the wrong token was used to interact with the cell, you should treat these as unrecoverable errors by unwrapping the result.

pub fn try_borrow_mut<'l>(
    &'l self,
    token: &'l mut Token
) -> Result<&'l mut T, <Token::Checker as TokenChecker<Token>>::Error>

Fallible equivalent of TokenCell::borrow_mut, for runtime-checked tokens.

Since token mismatch is indicative that the wrong token was used to interact with the cell, you should treat these as unrecoverable errors by unwrapping the result.

pub fn as_ptr(&self) -> *mut T
