Methods

impl Integer

fn fit_signed(x: i64) -> Integer

Unstable (rustc_private)

Find the smallest Integer type which can represent the signed value.

fn fit_unsigned(x: u64) -> Integer

Unstable (rustc_private)

Find the smallest Integer type which can represent the unsigned value.

fn from_attr(dl: &TargetDataLayout, ity: IntType) -> Integer

Unstable (rustc_private)

Get the Integer type from an attr::IntType.

fn repr_discr(tcx: TyCtxt, hint: ReprAttr, min: i64, max: i64) -> (Integer, bool)

Unstable (rustc_private)

Find the appropriate Integer type and signedness for the given signed discriminant range and #[repr] attribute. N.B.: u64 values above i64::MAX will be treated as signed, but that shouldn't affect anything, other than maybe debuginfo.

Trait Implementations

Derived Implementations

impl Debug for Integer

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Hash for Integer

fn hash<__H: Hasher>(&self, __arg_0: &mut __H)

Feeds this value into the state given, updating the hasher as necessary.

fn hash_slice<H>(data: &[Self], state: &mut H) where H: Hasher

Feeds a slice of this type into the state provided.

impl Ord for Integer

fn cmp(&self, __arg_0: &Integer) -> Ordering

This method returns an Ordering between self and other.

impl PartialOrd for Integer

fn partial_cmp(&self, __arg_0: &Integer) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

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

fn le(&self, other: &Rhs) -> bool

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

fn gt(&self, other: &Rhs) -> bool

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

fn ge(&self, other: &Rhs) -> bool

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

impl Eq for Integer

impl PartialEq for Integer

fn eq(&self, __arg_0: &Integer) -> bool

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

fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl Clone for Integer

fn clone(&self) -> Integer

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
