Struct miri::concurrency::vector_clock::VTimestamp

pub(super) struct VTimestamp {
    time_and_read_type: u32,
    pub span: Span,
}

The time-stamps recorded in the data-race detector consist of both a 32-bit unsigned integer which is the actual timestamp, and a Span so that diagnostics can report what code was responsible for an operation.

Fields

time_and_read_type: u32

The lowest bit indicates read type, the rest is the time. 1 indicates a retag read, 0 a regular read.

span: Span

Implementations

fn time(&self) -> u32

fn set_time(&mut self, time: u32)

pub(super) fn read_type(&self) -> NaReadType

pub(super) fn set_read_type(&mut self, read_type: NaReadType)

pub(super) fn span_data(&self) -> SpanData

Trait Implementations

impl Clone for VTimestamp

fn clone(&self) -> VTimestamp

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for VTimestamp

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Ord for VTimestamp

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for VTimestamp

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for VTimestamp

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
