Struct embedded_sdmmc::Timestamp

pub struct Timestamp {
    pub year_since_1970: u8,
    pub zero_indexed_month: u8,
    pub zero_indexed_day: u8,
    pub hours: u8,
    pub minutes: u8,
    pub seconds: u8,
}

Represents an instant in time, in the local time zone. TODO: Consider replacing this with POSIX time as a u32, which would save two bytes at the expense of some maths.

Fields

year_since_1970: u8

Add 1970 to this file to get the calendar year

zero_indexed_month: u8

Add one to this value to get the calendar month

zero_indexed_day: u8

Add one to this value to get the calendar day

hours: u8

The number of hours past midnight

minutes: u8

The number of minutes past the hour

seconds: u8

The number of seconds past the minute

Implementations

impl Timestamp

pub fn from_fat(date: u16, time: u16) -> Timestamp

Create a Timestamp from the 16-bit FAT date and time fields.

pub fn serialize_to_fat(self) -> [u8; 4]

Serialize a Timestamp to FAT format

pub fn from_calendar( year: u16, month: u8, day: u8, hours: u8, minutes: u8, seconds: u8 ) -> Result<Timestamp, &'static str>

Create a Timestamp from year/month/day/hour/minute/second.

Values should be given as you’d write then (i.e. 1980, 01, 01, 13, 30, 05) is 1980-Jan-01, 1:30:05pm.

Trait Implementations

impl Clone for Timestamp

fn clone(&self) -> Timestamp

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Timestamp

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

Formats the value using the given formatter.

impl Display for Timestamp

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

Formats the value using the given formatter.

impl Ord for Timestamp

fn cmp(&self, other: &Timestamp) -> 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 Timestamp

fn eq(&self, other: &Timestamp) -> 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 !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for Timestamp

fn partial_cmp(&self, other: &Timestamp) -> 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.
