Struct swym::tcell::Ref

#[must_use = "Acquiring a Ref without using it unnecessarily increases the chance of transaction failure"]
pub struct Ref<'tx, T> { /* fields omitted */ }

A snapshot of a TCell valid for the duration of the current transaction.

A Ref can be obtained using TCell::borrow.

Trait Implementations

impl<'tx, T: PartialEq> PartialEq<Ref<'tx, T>> for Ref<'tx, T>

fn eq(&self, other: &Ref<'tx, T>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Ref<'tx, T>) -> bool

This method tests for !=.

impl<'tx, T: PartialOrd> PartialOrd<Ref<'tx, T>> for Ref<'tx, T>

fn partial_cmp(&self, other: &Ref<'tx, T>) -> Option<Ordering>

fn lt(&self, other: &Ref<'tx, T>) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Ref<'tx, T>) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Ref<'tx, T>) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Ref<'tx, T>) -> bool
